A one-armed robber jumped from a window to escape police – and broke his arm.

James Deacon, 28, of Tristram Close, Sompting, was carrying a baseball bat when he burst into a firstfloor flat in Shelley Road, Worthing, on January 26, with another man who was carrying a shotgun.

They threatened three men and a woman living in the flat and demanded drugs and cash.

The alarm was raised and police were called. Both men escaped by climbing out of a window and jumping on to the concrete below.

Deacon injured his leg and broke his arm when he landed and was arrested.

He admitted aggravated burglary when he appeared at Chichester Crown Court and was sentenced to four and a half years in prison.

The other man has never been traced.

Police said they found no evidence of drugs inside the flat.

Anyone with information about Deacon’s accomplice should call police on 0845 6070999.
