Police are continuing their search for missing man Aslan King in bushland surrounding the Princetown area.

The 25-year-old was camping with friends at a camping ground on Old Coach Road when he had a medical episode and hit his head about 2am.

The British national has suddenly got up and run from the area into surrounding bushland near the bridge south of the camping ground.

His friends conducted a search but have been unable to locate him.

It’s believed Aslan, who has been in Australia for two weeks on holidays, may be disorientated and become lost in the bush.

The search will include the police Air Wing helicopter, horses from the Mounted Branch, off-road motorcycles from the Special Solo Unit, Search and Rescue members, local police, SES volunteers and Parks Victoria employees.

Police have released an image of Aslan taken yesterday in the hope someone may recognise him.

He was wearing the same clothing pictured except the black jacket.

He’s described as Caucasian, with a medium build, dark short hair and was wearing trackpants, a light grey t-shirt with grey hoodie, green Reebok runners and may possibly have blood on his forehead.

Anyone who may have seen Aslan or with information on his whereabouts is urged to contact Warrnambool Police Station on 5560 1333.
