The search to find a British tourist who went missing on Victoria’s Great Ocean Road on Saturday will be scaled back for the night and resume on Monday.

Aslan King, 25, was camping with friends at Princetown, near the Twelve Apostles, when he hit his head about 2am on Saturday.

He suddenly got up and ran off into the bushland but his friends could not find him.

The police helicopter, officers riding horses, off-road motorcycles, and ground crews have been looking high and low to find King, who has been in Australia for two weeks.

King is of medium build with short hair and was wearing trackpants, a light grey T-shirt and hoodie with green Reebok sneakers when he fled.

He may have blood on his forehead.
