Authorities search for missing UK tourist in Australia

Authorities have resumed the search for a British tourist who has been missing in Australia since Saturday.

Aslan King, 25, was camping with four British friends in the Victoria state town of Princetown near the Twelve Apostles, where it's believed he hit his head after an apparent seizure, local media reported.

King then ran away from the campsite early Saturday and has been missing since, according to local media.

Emergency services mounted a search on foot, horseback, and through the air.

Sergeant Danny Brown of Victoria State Police told reporters that police are not investigating foul play.

Police said they've expanded the search Monday to a four-kilometer radius to include waterways around the campsite.
