A gang of teenagers who bashed a 59-year-old man during a frightening home invasion returned to the scene of the crime while the victim was in hospital to steal his car, police say.

The group of six to eight young men knocked on the door of David McGregor’s Narre Warren home in Melbourne’s south-east just before 10pm on Monday.

Mr McGregor said when he answered the door, the young men forced their way in and kicked and punched the man to his ribs and head.

‘‘I’m pinned to the floor and my arm is pinned behind my back [then] someone’s come up beside me [and] kicked me in the face, somone’s kicked me from the other side, I didn’t see what it was, it was a blur,’’ Mr McGregor told radio station 3AW on Tuesday morning.
