During the attempted burglary on 4 April, Richard Osborn-Brooks is thought to have taken a screwdriver from 37-year-old burglar Henry Vincent and fatally injured him.

Osborn-Brooks, 78, was arrested on suspicion of murder but was released without charge afterwards.

He and his disabled wife Maureen look unlikely to return to their house in Hither Green, South London, after the incident. It is thought that they are currently in a police safe house as a result of fear of reprisals from Vincent's associates.
