A 38-year-old schizophrenic man launched an unprovoked knife attack on a train passenger after yelling 'I want to kill all the Muslims', a court heard today.

Adrian Brown was said to be suffering a 'severe psychotic episode' when he stabbed Muhammed Ali on a London Overground carriage in the south of the capital.

The intervention of other passengers on the train - which was travelling between Honor Oak Park and Forest Hill - might have saved the victim's life, the trial heard. Brown accepted that he carried out the attack, but pleaded not guilty to a charge of attempted murder on the grounds of insanity at Southwark Crown Court.

Prosecutor Alan Kent QC told the court: 'The defendant was living in a hostel on the morning of December 12 (2016), he left that hostel armed with a knife - he was determined to find and kill Muslim men.

'He went to the train station at Honor Oak Park which isn't very far away from the hostel where he was living. He had with a knife which he took from the hostel.

'He walked up and down the train threatening passengers, threatening death to Muslims while looking for any Muslim men to stab and kill.

'He saw the victim, Mr Muhammed Ali, who was sitting on the train with his wife. The defendant approached Mr Ali who was sitting down and repeatedly stabbed him to his head and his body. 'Other passengers on this train came to Mr Ali's rescue and it would seem it was their bravery coupled with medical attention from a doctor and a nurse who happened to be on a train, that they may well have saved his life through their quick medical intervention.'

Mr Ali suffered injuries to his head and torso, as well as a punctured lung. Jurors at the trial of issues will consider whether Brown was insane at the time of the attack.

He is also accused of carrying a knife and assault by beating of Filipe Dias, who worked at the hostel, during an earlier incident, both of which are denied on the grounds of insanity.  The court heard Brown had become agitated over the absence of hot water and set upon Ms Dias, who had previously confiscated knives from him.

Mr Kent said: 'He was unhappy about a problem there with the hot water system.

'But there was something much more serious going on in his head at that time because what he suddenly came out with is "I'm going to destroy Isis, Isis are the problem".'

Ms Dias then came across his path and was grabbed by the throat and shouted at. 'As he left the defendant was heard to say: 'I'm going to kill some Muslims'.'

When at the station he was allegedly heard saying 'where are all the Muslims? I am going to kill all the Muslims' before holding a knife to the throat of another woman, who was unhurt.

He is then said to have spotted the victim, whose wife was wearing a hijab and a burka.

'He called him a "f***ing Muslim" before attacking him with a knife, stabbing him repeatedly and repeatedly shouting "f***ing Muslims" as he did so,' Mr Kent said.

'He stabbed Mr Ali numerous times, the crown say, clearly in an attempt to kill him.'
