The suspect, who is white and dressed in a black padded coat with the hood up and half his face covered, can be seen entering the shop and waiting near the counter.

He is then seen in a scuffle with the guard, who tries to fend off the suspect with his makeshift weapon as the thief escapes with the cash delivery.

The victim was taken to hospital for treatment for injuries to his head and shoulders and was released later that day, Tuesday February 16.

The Metropolitan Police Flying Squad have appealed for witnesses to call 020 8785 8655.
