Detectives have returned to a graveyard to search for clues about the potential murder of Lee Boxell.

Police began excavating parts of St Dunstan's Church in Cheam last summer, using state of the art ground penetrating radar from the Royal Engineers, and have now returned to continue their search.

Cheam schoolboy Lee Boxell was last seen in Sutton High Street on September 10, 1988.

Until recently police investigating the disappearance of the then 15-year-old believed he had gone to watch a football match at Selhurst Park.

But a recent Crimewatch appeal dismissed that idea, and now police are working on the assumption he walked to Cheam, and could have attended The Shed - an unofficial youth club where youngsters used to drink and smoke, which was based in the grounds of the church.

Following the appeal, which was aired on February 14, days before what would have been Lee's 40th birthday, police received more than 40 calls from members of the public.
