A MAN in his 70s was knocked to the ground and then robbed after being struck on the back of the head.

A man on a bike approached the 78-year old from behind on Sycamore Grove, Southend, before striking his head between 6.05pm and 6.10pm on Monday.

He fell to the ground before the robber searched his pockets and removed his wallet.

The suspect then made off on the mountain bike.

The suspect was a white man in dark clothing. He rode off towards Dryden Avenue.

Investigating officer, Dc Jonathan Holland, said: "This crime is particularly despicable as the robber was prepared to knock this man to the ground purely to steal his wallet.

"It would clearly have been extremely distressing for him, and I would really urge anyone who has information which could help solve this crime to get in touch.”

Anyone with information should contact Dc Holland, or his colleagues at Southend CID, on 101. Alternatively, call Crimestoppers anonymously on 0800 555 111.
