Dramatic moment police Taser a knife-wielding one-armed roller skater moments after he stabbed three victims

This is the dramatic moment police officers confronted a one-armed knife-wielding roller skater - moments after he allegedly stabbed three people.

Benjamin Bridgeman, 38, who has schizophrenia, is on trial accused of attempted murder following the shocking attacks in Knowle, Bristol, earlier this year.

He faces eight charges in total at Bristol Crown Court, including three counts of attempted murder. 

In CCTV footage shown to the court, the accused appeared to stab a man in the back before continuing on and seemingly slashing another in the head on February 25.

Members of the public then raised the alarm and went after Bridgeman - with one also suffering stab wounds as he tried to intervene.

The defendant skated away towards the centre of the city before being stopped by the authorities with a taser. Bridgeman has pleaded not guilty to all charges.

Evidence from forensic psychiatrist Dr Stephen Attard was read to the jury.

He twice interviewed Bridgeman and, asked whether he knew what he was doing was legally wrong, Dr Attard concluded: 'On balance, I think the defence of insanity should be available in this case.'

The court heard the defendant, who was born without his left arm, had a history of OCD since the age of 15. He used cannabis and LSD to try to control his social anxiety, though he had stopped using cannabis a week before the rampage.

The day before, he told a psychiatrist he thought he 'was going to be taken away to be sacrificed'.

Bridgeman is now facing eight charges - including three counts of attempted murder.

He is also accused of three counts of wounding with intent to cause grievous bodily harm, attempted wounding with intent and having an offensive weapon.

Richard Posner, prosecuting, has told the court the defendant was employed and of good character at the time of the incident but had suffered a psychotic breakdown.

He added the jury will have to decided if the he 'was insane when he did what he did' - as experts have agreed he was suffering from a 'disease of the mind'.

The court has heard that a special verdict of 'not guilty by reason of insanity' is available.

The trial continues.
