Police are appealing for help to trace a missing teenager.

Fifteen–year-old Aidan Chivannes is missing from his home in Watford.

Aidan is a black male and is around 5 ft 6 inches tall. He is of slim build and wears a diamond stud earring in each ear. He was last seen carrying a black Nike air rucksack.

Police and his family are growing increasingly concerned for his welfare.

Sergeant Andrea Dalton, who is leading the investigation, said: "Aidan, we are all growing increasingly concerned for your welfare, please phone home or contact us and let us know you are ok.

“You are not in any trouble, everyone cares for you and they just want you home safe.”

Anyone who knows of Aidan’s whereabouts or who may have seen him, is asked to contact Sergeant Dalton on 101.
