Police are to dig at a cafe looking for the remains of possible Fred West victim Mary Bastholm after blue material was spotted there - the same colour as the coat she was wearing when she vanished.

Gloucestershire Police have decided to dig up the basement of the Clean Plate Cafe after examining the evidence.

Mary, 15, who worked at the diner, was wearing a blue coat when she disappeared in Gloucester in 1968.

Police have now revealed a production company filming a documentary at the Clean Plate tipped them off after finding an image of blue material in one area of the cellar.

Officers were called there on May 7 following suggestions a body may have been buried there.

West was a regular at the cafeteria, then called the Pop-In Cafe, and was previously suspected over her disappearance.
