A man wanted by police in connection with a string of armed robberies remains on the loose this morning.

Detectives last night named Jon Shirley, 23, as the man they want to speak to about an armed robbery at a BP garage in Cherwell Drive, in Marston, and 11 other raids around the Oxford area.

Supt Andy Murray, Oxford area commander, has warned members of the public not approach Shirley but dial 999 immediately if he is spotted.

Shirley is described as white, about 6ft, with distinctive, untidy dark hair and a pudding bowl style fringe, brown eyes, thick eye brows, a local accent and a slim build.
