A year ago to the day, Piotr Woroneicki was found dead in the streets of Clapham.

Now a reward of up to £10,000 is being offered by Crimestoppers for information that leads to the arrest and conviction of those responsible for the Polish national's death.

Detective Chief Inspector Mark Cranwell, who is leading the investigation into Piotr’s murder, said: “It has been a year since Piotr’s body was found on the street at Parma Crescent in Clapham, and whilst we are making headway in the investigation, we still want to hear from anyone who saw Piotr in the days before his death, or knows anything about who killed him or their motive for doing so.”

A special post-mortem examination held in July gave which gave the cause of death as compression to the neck, consistent with the 32-year-old being held in a headlock for a prolonged period.

Following the post-mortem result, the case was handed to DCI Mark Cranwell from the Met’s Homicide and Major Crime Command.

“Piotr was last seen alive at 11.32pm on November 22, 2017, at New Covent Garden Market where he appeared to be in reasonably good spirits," DCI Cranwell.

"He was found by a member of the public at 5am on November 23, some hours later, in Parma Crescent, which is approximately three miles in distance from New Covent Garden Market.

“A large quantity of class A drugs and close to £100,000 in cash was found in Piotr’s flat which leads us to believe he may have been involved in some form of criminality and that his death may be linked to an organised crime syndicate; however this has not yet been proven.

“I still want to hear from anyone who may have seen Piotr that night or knows anything about why he was killed.”

Detectives have previously released CCTV footage of numerous attempted break-ins at Piotr’s address on Clapham Common Northside.
