Police are desperately searching for a vulnerable missing teenager, who was lost in London during a visit to the capital with his family.

Benjamin Moorcroft, 15, from Shrewsbury, was last seen by his family in Covent Garden, Westminster , at around 8pm on Saturday (October 21), having a restaurant meal before his disappearance.

The vulnerable teen, who is alone in a city unfamiliar to him, suffers from epilepsy and has a mental age of between five and 10-years-old, said police.

Detective Inspector William Hodgkinson said: "Benjamin's disappearance is very out of character.

"He is alone in London, a place unfamiliar to him, and particularly vulnerable due to his epilepsy.

"Benjamin’s family and my officers are concerned for his wellbeing. Efforts to locate him are ongoing, but we need the public's help.

"We would urge anyone who believes they may have seen Benjamin in central London or further afield since his disappearance on Saturday night to get in touch as soon as possible."
