A terrified man jumped to his death to escape three brothers who beat him up after wrongly accusing him of stealing a mobile phone.
Pawel Pacholak, 37, leapt from a bathroom window, breaking his neck, as he fled Viktoras Tarasov, 39, of Croydon, Valodia Tarasov, 35, of Norbury, and Jurius Tarasov, 33, of Brixton, on January 12 last year.
Mr Pacholak suffered multiple serious injuries, including to his head, face and torso, and broke 11 ribs, either in the fall at the flat in Streatham or during the attack.
The three brothers were found guilty of manslaughter today at the Old Bailey after the jury concluded they were responsible for his death despite not inflicting the fatal injuries.
The court heard Mr Pacholak had been staying at a friend's house in Streatham High Street with several other people including Viktoras Tarasov, now of Aurelia Road, Broad Green.
The occupants had been drinking throughout the day of the killing before Valodia Tarasov, of Abingdon Road, and his brother Jurius arrived at about 10pm.
A confrontation broke out when the three brothers claimed Mr Pacholak had stolen Jurius's missing phone, which had in fact been lost earlier that evening.
The argument spilled onto the streets at 10.56pm before reigniting between midnight and 1.30am, during which time a loud noise was heard at the rear of the building, where a neighbour saw an apparently drunken man staggering before collapsing on the patio.
Mr Pacholak was found dead, slumped against a wall in Albert Carr Gardens, at 11.50am on January 13.
His body bore clear signs of an assault and police found "extensive" blood stains with in the house that occupants had attempted to clean up, while the first officers on the scene also saw Viktoras Tarasovs throwing red water out the back door. He claimed it contained blood from meat.
Detectives determined Mr Pacholak had taken refuge in an upstairs bathroom and tried to escape by jumping out the window, unknown to the other occupants. He landed face down and collapsed soon after.
The brothers were arrested days later and subsequently charged with manslaughter and perverting the course of justice for trying to clean the blood and giving false alibis in police interview.
They will be sentenced tomorrow.
Detective Chief Inspector Andrew Chalmers, of the Metropolitan Police's Homicide and Major Crime Command, said: "This has been a complex case with the prosecution needing to prove the defendants responsible for Pawel's death despite them not actually having pushed him from the window.
"The jury agreed that the victim was so scared of being further assaulted he felt he had no option but to escape via a window. He would never have taken such drastic action had he not been in great fear for his safety."
