Three men have been jailed for beating a homeless man to death in a "happy slapping" incident.
Gary Turner was attacked twice within a few hours
Gary Turner, 43, was attacked twice in the space of a few hours by the gang, in Stratford Broadway, east London, while they filmed it on a mobile phone.
Thomas Slater, 22, and David Selby, 23, were given life sentences and Muyazzim Rohman, 22, was jailed for 10 years.
The court heard that the men had attacked two other people before the final attack on Mr Turner.
Slater was ordered to serve a minimum term of 14 years while Selby was told he would serve a minimum of 12-and-a-half years.
The jury heard that the group filmed the first attack on Mr Turner, who was punched in the head as he was sleeping on a bench outside a library last September.
The trio filmed the first attack on Gary Turner
Mr Justice Bean said Slater and Selby had participated in the "repulsive practise of happy slapping" while Rohman filmed it and later showed it to a friend "as a form of entertainment".
At the time of attack Mr Turner was intoxicated and dazed.
A few hours later the men returned and punched and kicked him to death.
Slater was convicted of murder, Selby admitted murder and Rohman was found guilty of manslaughter last week.
Slater and Rohman were found guilty of GBH over the attack on another man, Antanas Danilius, who was seriously injured. Selby pleaded guilty to the GBH charge.
Police said they also attacked a third man, who has yet to come forward.
