Two men are being hunted by police after a man was beaten to death in a homophobic attack on Clapham Common in south London.
Jody Dobrowski had been visiting a friend before he was killed
Jody Dobrowski, a 24-year-old bar manager from south-east London, was found unconscious in the early hours of Saturday but died later in hospital.
Detective Chief Inspector Nick Scola described the attack as abhorrent.
He appealed to the gay community to help catch the killer and asked anyone attacked on the common to come forward.
Speaking from Clapham Common on Sunday afternoon, DCI Scola said: "He was the victim of a sustained and violent assault.
"There were other people in the area at the time of the attack and homophobic insults were heard. For that reason I am convinced it was a homophobic attack."
He said it was not known whether Mr Dobrowski was gay but officers were looking closely at his lifestyle and background.
"Certainly those who carried out the attack thought he was gay," he said.
He added that he particularly wants to trace Mr Dobrowski's movements between 2215 BST, when he left a friend's house near the common, and just after midnight when the police found him lying unconscious.
A post-mortem examination on Sunday showed the cause of death was severe head, neck and facial injuries.
'Others at risk'
The first suspect is described as white, between 20 and 30, 6ft tall, with shaved hair, while the second man is also white, about the same age, but said to be shorter and stockier.
Bob Hodgson, from the Lesbian, Gay, Bi-Sexual and Transgender advisory group, said: "The main focus at this time is to catch the people that murdered this young man.
"This is a time for people from the community to come forward if they know anything at all.
"If you don't come forward with what you know you could potentially be putting other people at risk in the future."
Borough Commander Jo Royle, from Wandsworth police, said: "I know the concerns and worry this attack will have. We need you to help us.
"You may also have vital information that can assist us capture the people that committed this murder."
