Five people caught on closed-circuit TV taking part in a "sickening" attack in which an unconscious man was kicked in the head have been jailed.

Peter Shaw, 20; Andrew Harbourne, 19; Joshua McErlean, 19; Gemma Stafford, 18; and an unnamed17-year-old have been jailed for the attack in Manchester, England on March 15.

After an argument with the 27-year-old victim, the group bashed and robbed the man, an act police described as "mindless violence at its worst.

”The victim was knocked unconscious but Shaw, Harbourne, McErlean and the 17-year-old continued to punch, kick and stamp on the victim, as blood started to pool around his head, police said. The video showed three of the group running off while Shaw and Stafford stayed behind, with the young woman rifling through the victim's pockets to steal money and cigarettes.

Stafford even rolled the victim over to get access to his front pockets while Shaw continued to kick the victim in the head.

Shaw took one last running kick at the victim's head before they left him for dead, police said. Detective Sergeant Lee Johnson of Greater Manchester police said it was "sheer luck" that the victim suffered only minor injuries.

"The ferocity of the blows to his head could have caused serious and lasting damage. Their actions were sickening to watch and is mindless violence at its worst," he said.

Stafford was sentenced to 18 months on Tuesday after pleading guilty to violent disorder and robbery. Shaw was sentenced to four years after pleading guilty to causing grievous bodily harm with intent and violent disorder.

Harbourne was sentenced to four years after pleading guilty to violent disorder and robbery.
