A knife attack might have been prevented if the perpetrator had received better mental health care, an investigation by England’s Health Ombudsman has found. 

In November 2020, a 31-year-old man stabbed a man in his thirties, just one month after being discharged from the care of Kent and Medway NHS and Social Care Partnership Trust, now called Kent and Medway Mental Health NHS Trust. He was arrested and later detained under the Mental Health Act. After the attack he was diagnosed with schizophrenia.  

The Parliamentary and Health Service Ombudsman (PHSO) found a series of failings by the Trust in the 12 months leading up to the stabbing. These included poor care planning and discharging the patient without reviewing his risk level. 

The Ombudsman concluded that these failings might have contributed to the man’s mental health decline.  Had he received safe and appropriate care, the stabbing might not have occurred. 

PHSO has repeatedly raised concerns about systemic failings in mental health services. In 2024, the Ombudsman published a report highlighting failures in transferring people with mental health conditions out of services. The report found failures in planning, communication, and continuity of care, and called for services to be more holistic, joined up, and person-centred. 

Rebecca Hilsenrath, Chief Executive Officer of PHSO, said, 

This is a sad case involving a vulnerable man who posed a risk not only to himself, but to others. A risk that tragically became reality when he attacked an innocent member of the public. It highlights the stark consequences of poor mental health care, not just for patients, but also for their families, carers and even members of the public. 

 

“The patient’s mother repeatedly raised concerns about her son’s deteriorating condition and the risks he posed. She was so fearful that she felt forced to hide in her car rather than remain in the home they shared. Despite her repeated pleas for help, she was badly let down by the Trust and left to cope alone without the support she urgently needed.  

 

 

“For over a year, she endured a frightening and distressing situation. During periods when her son was in crisis, her requests for help went largely unanswered, leaving her in fear for her safety. Good mental health care must include truly listening to families and using their unique insight to inform care decisions. 

 

 

"There is still significant work to be done to embed a culture within mental health services that learns from past mistakes. While there have been some improvements, including steps towards reform of the Mental Health Act and ongoing Government inquiries, these must lead to real change on the ground – change that improves services and keeps people safe.”   

The Ombudsman investigated after the patient’s mother, 57, complained about the care and support the Trust provided to her as she tried to get help for her son. 

The woman says her son began struggling with symptoms of paranoia and anxiety in early 2019. He was detained by police and admitted to hospital in October that year before being discharged later.  

Phone records show the man’s mother repeatedly contacted the mental health team in April and May 2020. She reported that her son had been ripping up blinds and carpets, placing furniture in the garden and blocking her from leaving the house. She told staff she was frightened and, on occasions, was hiding in her car for hours while calling and asking for help. 

Our investigation found that the Trust knew that the man was experiencing a crisis, in need of a medical review, and that his mother was not coping. However, it failed to develop a care plan or crisis plan and did not provide information or support to his mother as his designated carer. 

Instead, staff repeatedly told her to contact the police, despite knowing this was a mental health matter and the police would be unlikely to intervene unless a crime had been committed. The Ombudsman found this fell far short of the Trust’s own policy and national clinical guidelines.  

The man was later arrested for alleged criminal damage and detained in hospital. In June 2020, he was discharged to the community mental health team, who were responsible for assessing his risk and providing his care. 

Between June and October 2020, the man received three phone calls but was not seen by the care team in person.  The Trust did not develop a risk assessment or crisis plan. Not did they review his medication despite clear indicators of non-compliance and relapse. 

The Ombudsman described this as a failure to undertake an essential and fundamental aspect of care planning and unsafe clinical practice. 

Further failings occurred when he was discharged from the Trust’s service in October 2020. Staff had not seen him face-to-face since June and did not take appropriate steps to contact him when he did not attend appointments. He was not informed he had been assigned a new care coordinator. The coordinator was also unaware he was subject to a care plan or that his mother was his designated carer. 

The Ombudsman found the failings left the man’s mother in distress for over a year and caused her to fear for her safety.  

The Trust’s internal investigation was also flawed. The mother was not informed that confidential information would be included in their report and she was not given the opportunity to contribute, contrary to NHS England’s framework. 

PHSO recommended that the Trust writes to the woman to acknowledge the failings in her son’s care, the lack of support provided to her as his carer, and the serious distress and anxiety this caused. The Ombudsman also recommended the Trust creates an action plan to improve its services. 

The Trust was also asked to pay the mother £240 for costs to repair property damage when her son was in crisis in May 2020, as well as £3,700 in recognition of the long-term distress and worry caused by its lack of support. The Trust has agreed to comply. 

The mother said the experience caused long-term trauma and left her withdrawn for two years. 

She said, 

I know my son and I was telling the community mental health team for months that he was not well and that it was getting worse. I woke up one day and he was standing in my bedroom staring at me.  

 

 

"I was too scared to be in my home, so I sat in my car for hours calling staff begging them to help. For months I was telling them he was in psychosis. I was terrified. They offered no real help. 

 

 

"They failed my son, they failed me, and they failed the person he hurt. Before he committed this crime, he had never been violent. I have no doubt that he hurt someone because of the failings of the community mental health team. People with mental health issues are vulnerable and won’t necessarily speak up, so they should have listened to me and took on board what I was saying.  

 

 

"I know the NHS is under pressure. But when you tell health professionals that your son is going to kill themself or hurt someone, and they question why you are scared if he hasn’t hit you, something has gone badly wrong. That is not pressure, that is reckless behaviour in a broken system.”  

Julian Hendy, founder of the Hundred Families charity for families affected by mental health homicides in Britain, said, 

In our experience most incidents like this occur when seriously unwell people are unable to access the care and treatment they need. Listening to families is key. Often they will have crucial information about the patient’s history, presentation, and behaviour when clinicians are not present. Failing to listen means services remain poorly informed about the risks patients present to themselves, their families, and others. This is unfortunately not new.  

 

"For over 30 years, NHS inquiry reports have made recommendations about the need to plan care effectively, assess risk and discharge properly and listen to families, yet there is little evidence services are learning. Listening to families and providing timely, effective care saves lives. It helps prevent terrible incidents like this.” 

A Kent and Medway Mental Health NHS Trust spokesperson said, 

This was a deeply serious and complex case, and we recognise the distress experienced by the family. 

 

"Concerns raised in 2021 were fully investigated, including through close engagement with the Parliamentary and Health Service Ombudsman, and we have been open and transparent throughout that process. 

 

"We apologise for where care and support did not meet expected standards and have taken action to strengthen community mental health services in line with the National Community Mental Health Framework.”

The Local Government and Social Care Ombudsman has taken the unusual step of issuing a further report against South Kesteven District Council for it refusing to pay a remedy to a man who asked for homelessness support.

The Ombudsman found that the council failed to properly consider whether it had a duty to provide the man with accommodation while it processed his homelessness application in early 2024. Despite the man telling the council he had been admitted to hospital and that medical staff believed his housing situation was affecting his health, the council did not demonstrate that it considered the correct legal tests when deciding whether it should offer him interim accommodation.

The law sets a deliberately low bar for councils to provide accommodation whilst considering whether to provide long term housing to an individual. Councils only need to have reason to believe someone may be homeless, eligible and vulnerable. The Ombudsman found evidence South Kesteven consistently applied a much stricter test and also failed to revisit its decision when it received new information about the man’s health conditions and welfare.

In its original report, published in August 2025, the Ombudsman made a number of recommendations to the council. The council has since complied with only two of them and has refused to: apologise to the man, pay him a combined financial remedy of £1,175 for the distress caused and remind its homelessness staff of the correct legal test for interim accommodation

Amerdeep Clarke, Local Government and Social Care Ombudsman said:

“The duty to provide interim accommodation exists precisely to protect people in situations like the one this man found himself in. The threshold is deliberately low, and councils must apply it correctly.

“The council has told us the correct test was applied but was not recorded properly due to an error in writing rather than consideration. The public have a right to expect public bodies to keep accurate records about them. Accurate record keeping is central to good administrative practice and transparent decision making.

“In this case, not only did South Kesteven District Council leave a vulnerable man sleeping rough when it should have housed him, it has now refused to properly remedy that injustice.

“We do not issue further reports lightly and I would urge the council to reconsider its position and comply with our recommendations.”
