A man has suffered serious injuries during a violent home invasion at Thomson. It's believed up to four people forced their way into a property in Olney Drive just before one this morning. Police say the offenders entered a bedroom where they seriously assaulted a 31-year-old man. The victim managed to make his way to a neighbour's house and raise the alarm. Ambulance Victoria says the man was taken to Geelong Hospital in a serious condition with injuries to his arm. He is due to undergo surgery today. Detective Acting Senior Sergeant Gary Wilson says the offenders then stole a 2002 black Holden Statesman and an unregistered motorcycle.
