Investigations are continuing after a 23-year-old man was shot dead by police in south London.
A fingertip search of the alleyway was carried out
He was shot by officers who were trying to arrest him after he had failed to appear in court to face firearms charges on Wednesday.
The man was pronounced dead in Raymead Passage off London Road, in Thornton Heath, at about 1125 BST. A hand gun was found, Scotland Yard said.
A 19-year-old man arrested at the scene was released without charge.
Eye witnesses said they heard two shots fired.
The Independent Police Complaints Commission (IPCC) is investigating.
Richard Offer, a spokesman for the IPCC, said: "We were notified shortly after the incident, it is mandatory, we have to be informed of such incidents."
"We have got to find out what exactly happened, where he was
and where the firearm was, all this has to be investigated."
A forensic examination of the gun was to be carried out and experts carried out a fingertip search of the alleyway.
