Police have launched a murder probe a year after a man was allegedly strangled in what officers believe was a gang hit linked to an organised crime syndicate.
The body of Piotr Woroneicki, 32, was found dumped in Parma Crescent in Clapham Junction, south London, in the early hours of November 23 last year.
A post-mortem found he died from compression to the neck, possibly from being held in a headlock. A £10,000 reward has been offered in a bid to solve the murder.
In the days around Mr Woroneicki’s death, two men tried to break into his home in Clapham Common North Side on five occasions. It is not clear if they were the same men each time.
Officers later found around £100,000 in cash and a large stash of Class A drugs at the address.
CCTV footage has been released of the suspects as they tried to gain entry.
Detective Chief Inspector Mark Cranwell appealed for anyone who knows the men in the footage to come forward.
"If you think you do know or recognise them, we'd urge you to call us as soon as possible," he added.
"What makes it even more peculiar is that we know that when officers entered the flat after the actual break in, nearly £100,000 in cash was in the living room along with a significant amount of Class A drugs.
"Why would someone break into a property and leave that big an amount of cash untouched?"
He said the murder may have been a "targeted hit" as part of "gangs or organised crime"
Mr Woroneicki, from Poland, was last seen alive on the evening of November 22 at New Covent Garden Market.
Mr Cranwell added: "There are about five-and-a-half hours that Piotr is unaccounted for where we don't know who he may have met with or spoken to and it's crucial that we fill in these missing hours to help solve his murder and convict the person or persons responsible for his death.
"The night Piotr died there was torrential rain that some could describe as 'biblical proportion'.
"I'm hoping that by mentioning this, it might jog somebody's memory."
A Crimestoppers reward of up to £10,000 is being offered for information that leads to the arrest and conviction of those responsible for Mr Woroneicki's murder.
