Police are seeking two men who robbed a sub-post office in Lower Horsebridge, near Hailsham.
The pair entered the North Street store just after 10am on Saturday (May 24) and threatened a member of staff with a knife. A man in his 60s suffered bruising to his arm and should as he tried to prevent one of the men getting through the counter door.
The pair made off with several thousand pounds.
There were no customers in the post office at the time and the other member of staff was not hurt.
The robbers fled in a maroon older style Ford Escort, which drove away northward in the direction of the A267 and Heathfield. It was found abandoned in Hellingly shortly afterwards.
One of the suspects, who had the knife and took the cash, is described as in his late twenties, medium build, about 6’, wearing a black hoodie and scarf.
The other suspect is described as in his early twenties, about 5’10”, wearing a grey hooded top, grey jogging bottoms, and a black scarf. He wore a small black rucksack on his back.
It is not yet known whether there was a third man driving the car.
Detective Sergeant Suzy Joseph said, “We would like to hear from anyone who saw the men enter or leave the store, or who saw the car after it left the scene.
