A teenager who shot a man dead in a drug dealing turf war has been sent to Broadmoor mental hospital.

Mohammed Ali, 19, blasted 21 year-old Mahamoud Jama in the chest with a shotgun as they tussled over the weapon at a block of flats.

The victim bled to death two hours later after telling his friend to say sorry to his mother ‘for every bad thing he had ever done in his life.’

Ali was charged with murder but claimed that the gun went off accidentally during a confrontation at Whyteville House, in Upton Lane, Forest Gate. He claimed that he only took the single-barreled weapon to the scene to scare off a group who objected to him dealing drugs in the area.

A jury at the Old Bailey cleared him of murder but convicted him of manslaughter and possession of a firearm with intent to endanger life.

Judge Jeremy Roberts QC said that Ali would normally have been jailed for at least six years for protection.

But since his conviction psychiatrists have diagnosed him as suffering from psychosis and personality disorder traits. The judge decided to make orders under sections 37 and 41 of the Mental Health Act so he can be treated indefinitely at a secure unit.

Judge Roberts said: “Mr Ali got into trouble with a number of drug dealers who resented him encroaching on their territory. He got a shotgun so he could intimidate this rival group. They chased him up to the first floor, attacked him and beat him about the head. There was a struggle and the gun went off. It was either an accident or in self defence but it all resulted from Mr Ali taking a loaded gun with him.
