Footage shows a group of six police officers in Epping around 4.10pm pinning the man to the ground, with one cop reportedly stomping on his hands.
The father-of-three was at the Northern Hospital waiting for a mental health bed but wanted to leave after sitting in emergency for more than a day.
Staff at the hospital then called for police to escort him in, where the violent arrest was taking place outside on Cooper Street.
A CIRT Senior Constable has been suspended. This follows the release of confronting vision showing an officer stomping on the head of a mental health patient. The father of three (who admitted himself to hospital but spent a day waiting for a bed) is still in a coma. @9NewsMelb pic.twitter.com/A8j8rbbWaH
