A random attack in south Edmonton early Saturday morning has left a 42-year-old man in a medically-induced coma.

Police say the man was waiting for a friend outside a medical centre at 104th Street and 51st Avenue around 1:15 a.m. when he was viciously beaten by several men.

The man was rushed to hospital after sustaining multiple head injuries.

Investigators have found video surveillance that shows a group of drunk men walking near a nightclub on 51st Avenue near 103rd Street.

Three of the men are seen leaving the group and walking into the parking lot where the assault occurred.

Police also believe the suspects may have eaten at a nearby fast food restaurant prior to the attack.
