Ryan Stewart has been missing since Monday night after he was last seen in South Lanarkshire.

A police helicopter and mountain rescue teams have been called in by police to help in the search for the 18-year-old.

The teenager was last seen by friends at 11.30pm at open ground near a quarry off Carscallon Road in Hamilton.

Inspector Mark Leonard, of Hamilton Police Office, said: "Ryan hasn't been missing before and this is completely out of character for him. His family and friends are becoming increasingly concerned for his wellbeing.

“Extensive enquiries are ongoing in the local area however, despite searches involving the police helicopter, mountain rescue team, dog unit and specially trained search advisors, Ryan hasn't yet been traced."

Mr Stewart is 6ft, of slim build with short dark hair and a spotty complexion. When last seen he was wearing a black and red tracksuit.
