Investigating officer Detective Chief Inspector Tony Nash of the Homicide and Serious Crime Command said: "Wieslaw Czyrak was subjected to an act of mindless violence which led to his fatal heart attack.
"This case is another illustration of pack mentality where despite it being unclear who delivered the fatal blow, the four involved, who have shown no remorse, are guilty and will now spend time behind bars.
"On behalf of my team, I would like to thank the extended Polish community in north London for their support and Cryzak’s family for their dignity in the most testing of circumstances."
Police were called by the London Ambulance Service just after 21:40 hours on Wednesday 17 June 2009 to reports of a man injured at the rear of Aldi’s in Tottenham High Road N17, near Parkhurst Road.
A man suffering a head injury was pronounced dead at the scene. He was Wieslaw Czyrak, 46, a Polish national of Newlyn Road, Tottenham.
A post-mortem examination gave the cause of death as a heart attack.
Mr. Czyrak, who had been in the UK for several years, lived in the local area and worked casually.
On the night of his death he attended a squat in Tottenham High Road to drink with the occupants. At approximately 21.15 hours, [B] and [O] went to the squat and began to prepare Class A drugs.
Mr. Czyrak objected to their actions and a brief argument ensued.
[B] and [O] left the squat, returning soon after with [L] and [M].
The group attacked Mr. Czyrak with a length of wood, hitting him with the implement and repeatedly kicking and punching his head and body.
Following the attack, the suspects left the scene.
London Ambulance Service (LAS) were called by an occupant at the squat and police attended.
One man [A] was arrested at the scene and a further 10 people – nine men (C/D/E/F/G/H/J/K) and one woman (I) – were arrested at addresses nearby. They have all since been released without further action.
Two 26-year-old men [B & L] a 30-year-old man [M] and a 20-year-old man [O] were subsequently arrested. They were bailed pending further enquiries to return to an east London police station on 14 December, and subsequently charged with the murder of Wieslaw Czyrak.
They were dealt with as above.
