Police are offering a £15,000 reward over the murder of a teenager stabbed to death in a park.
Jamil Palmer, 18, was found slumped in the road near Evans Grove in Feltham, Hounslow, west London, with a stab wound on May 6.
Detectives have also released a photograph of a Somalian man who had "an altercation" with Mr Palmer earlier that day.
Officers want to speak with Mahamed Barre, 18, who received a head injury in the disagreement and may have required medical treatment, Scotland Yard said.
Detective Chief Inspector Noel McHugh, of the homicide and major crime command, said: "I am seeking help from the local community to help locate Mahamed Barre. I would ask anyone who knows of his whereabouts, or has any information that could assist us, to come forward.
He added: "I also appeal directly to Mahamed Barre to present himself at a police station so this matter can be dealt with."
Four teenagers - two 16-year-olds and two 15-year-olds - have previously been charged with Mr Palmer's murder.
The £15,000 reward is being offered for information leading to the arrest and prosecution of those responsible for the murder.
