Police investigating the murder of a young father have named a teenager they want to question about the shooting.
Bradley Tucker is wanted by police for questioning
Bradley Tucker, 18, who is from Canning Town, east London, is sought for questioning about the death of Peter Woodhams, on 21 August.
Mr Woodhams, 22, is thought to have been killed after confronting youths in Canning Town. He had been stabbed in similar circumstances in January.
Mr Tucker has not been seen since the day of Mr Woodhams' death.
Det Sup Vic Rae said: "Following several appeals and a number of enquiries in the E16 area we would now like to speak to Bradley Tucker as part of our on-going investigation.
"We would urge anyone who may know of his whereabouts to contact us immediately."
He said anyone who saw Mr Tucker should not approach him but should dial 999.
Mr Woodhams was a satellite television engineer who lived with his fiancée and their three-year-old son.
Mr Woodhams had a young son
He was stabbed on 21 January, apparently after confronting a gang for throwing a stone at his car. His fiancée has said a group of youths continued to intimidate them following that attack.
At about 1900 BST on 21 August, Mr Woodhams was shot near his home. It followed a confrontation with a group of youths outside a parade of shops.
He staggered home and collapsed in front of his fiancé, dying shortly afterwards.
The police are themselves being investigated about their response to the stabbing in January.
An independent inquiry was launched, after his family said they had repeatedly called police after the attack, but had not been satisfied with the response.
Dep Com Paul Stephenson has said, based on what had been seen so far, aspects of the police response to the stabbing had been "unacceptable".
A review has been ordered of all outstanding investigations into GBH assaults across London.
