A teenager has been convicted of the manslaughter of 17-year-old Usaama Ali in Acton in October 2015.

The 17-year-old boy had earlier entered a plea of guilty to manslaughter, and on Monday, at Isleworth Crown Court, a jury found him not guilty of murder.

A murder investigation was launched after police and London's Air Ambulance were called at around 12:50hrs on 16 October 2015 to Crown Street in Acton.

Officers found Usaama, who had a stab wound to the heart, and, together with two local doctors and other members of the public who had rushed to help him, they carried out first aid and tried to save his life. 

Usaama was taken to St Mary's Hospital where he was pronounced dead at 14:00hrs that day.

Detective Chief Inspector Rebecca Reeves, who led the investigation, said: "Usaama's family are devastated by the loss of a son and brother. Why exactly this stabbing happened remains unclear.

“But what may have started out as a disagreement between two teenagers resulted in the death of a young man. 

"It would not have done so if the defendant had not decided to carry a knife with him that day. He is now facing a prison sentence for manslaughter. 

"This is a tragic case which shows the consequences of young people carrying knives on our streets."

The defendant will be sentenced on 5 September at Isleworth Crown Court.
