Police are hunting a robber who punched a post office security guard in the face.
CCTV footage has emerged showing the suspect attacking the 50-year-old guard from behind at the post office on Hampstead High Street, north-west London.
The suspect is white, and dressed in a black padded coat with his hood up and half his face covered.
In the video he enters the shop and waits near the counter, before appearing to scuffle with the security guard.
The guard removes his helmet and swings it at the attacker, but only manages to hit his arm.
The thief then escaped with the cash delivery.
The victim suffered injuries to his head and shoulders, and was rushed to hospital for treatment. He was released later that day, on February 16.
