A drug dealer caught after he left his photo identification in a discarded jacket stuffed with heroin and crack cocaine has been jailed, police said.
Mohammed Mahmood, 30, was found guilty of possession with intent to supply Class A drugs worth around £6,000.
Police officers found the jacket, which had been thrown from a balcony, after being called to reports of a disturbance at the Hastings House block of flats in Woolwich on November 11 last year.
Inside they found 100 wraps of crack cocaine and 197 wraps of heroin as well as Mahmood's ID.
He was arrested nearby and detectives later discovered CCTV footage showing him wearing the jacket moments before it was found.
Mahmood, of Robert Street, Woolwich, was sentenced to six-and-a-half years in prison at Woolwich Crown Court on Friday, the Metropolitan Police said.
Pc Martin Langley, from Greenwich borough, who oversaw the investigation, said: "I am extremely pleased that the jury has convicted him after being presented with what was overwhelming evidence.
"In Mahmood's eagerness to rid himself of a significant amount of Class A drugs, he forgot to remove his photographic ID from the jacket, which easily led to his arrest.
"The Greenwich Gangs Unit is committed to tackling the supply of drugs on the borough, and this sentence should act as a deterrent to those who choose to live this lifestyle with complete disregard for the impact their crimes have on the local community."
