Police are looking for a vulnerable teenage boy who is missing.
Solomon Thomas, 13, was last seen at 11.40am today at Falconer School in Falconer Road, Bushey.
He is white, 5ft 6in tall, medium build, and has blue eyes, short blonde curly hair and a scar on his head.
He was wearing a grey sweatshirt, black blazer and trousers, white shirt and green trainers.
Inspector Emma Adshead said: "Solomon is vulnerable and unfamiliar with the area, so we are increasingly concerned for his welfare.
"I would urge anyone who believes they may have seen him to call police as soon as possible on the non-emergency number 101."
Police helicopters were helping in the search for Solomon this afternoon.
