Forensic archaeologists have confirmed there are a number of “structural anomalies” in the cellar of the cafe they are searching for evidence linked to serial killer Fred West and a historical missing person case.

Police have been searching the Clean Plate cafe in Gloucester in connection with the disappearance of Mary Bastholm who vanished in 1968 aged just 15.

Serial killer West who died in prison in 1995 aged 53, was previously suspected over her disappearance.

Her body has never been found.

The detective leading the investigation says excavation work will now take place following “assessments at the scene, to establish if any human remains are present”.
