A 20-year-old man hanged himself in woodland within days of being discharged from a psychiatric ward, an inquest heard.

Jonathan Stent disappeared from his Ashtead home on September 7, 2011, and was found hanging from a tree near the station three days later.

Mr Stent had a history of depression, self-harming and using drugs including Ketamine, an animal tranquiliser taken as a recreational drug.

On June 11, Surrey Coroner Richard Travers issued a narrative verdict, which said he was discharged from the Epsom Hospital ward on September 6, the day before he went missing.

The verdict said: "He was discharged into the care of the Community Mental Health Team. No care plan had been prepared and no date had been set for him to see his care coordinator again."

The post mortem concluded that Mr Stent died from asphyxia as a result of hanging and toxicology evidence revealed that he took Ketamine before his death.

The Woking Coroner’s Court verdict said: "Jonathan Stent died from self-inflicted injuries but his intention was unclear."

Mr Stent had been admitted as a voluntary patient to the Elgar Ward after two overdoses in August 2011.

After five days, it was agreed he would go home but return a week later for an assessment and this happened for two weeks until September 6.

That day he had a final assessment, was introduced for the first time to his care coordinator and discharged.

In November his mother Caroline Stent told the court that after coming back from hospital he talked about being a burden and not wanting to have his whole life ahead of him.

Ms Stent told the court: "He said no one can help me. He said that several times: no one can help me. He spoke about being in emotional pain."

Mr Stent left a note, read out by the coroner, apologising for all the problems and saying his mother was the ‘best mum in the world’.

His father Stephen Stent, who had divorced his mother and only ran into his son by chance after his 17th birthday, sent him a letter while he was in hospital saying that he loved him.

Just before his death, Mr Stent had got a job at a garden centre in Ashtead. He worked for landscape gardeners and in various pubs after leaving school at 16.
