ROBBERS escaped with a box of cash from an Accrington post office.
Two men posing as customers entered the Blackburn Road shop and pounced as a guard was handing over a delivery.
An initial box had already been dropped off, but when the guard returned with another - thought to contain hundreds of pounds - one of the raiders snatched it and ran outside while his accomplice held the door open.
A speeding silver Mazda was seen leaving the scene and, despite road blocks being set up, the car was not traced.
Bashir Choglay, manager of the post office, was on duty at the time. He said: "It was all over very quickly. Fortunately, nobody got hurt and everybody is OK now, although we were a little shaken. It has never happened before and staff morale hasn't been affected. The police are dealing with it and we're getting on with our jobs."
Police cordoned off the post office and forensic teams scoured the area for clues to add to the robbers' descriptions, which were minimal.
The cash-snatcher was described as a large, heavily-built black man wearing a shirt and tie. His partner was a white man wearing a red cap.
The raid came just a day after three men held up a teenage attendant at the Supermart BP filling station on Hyndburn Road, Accrington.
One of the three, who were all thought to be mid-to-late 20s, thrust something which police think was a gun through the serving hatch, forcing the 19-year-old cashier to let them in.
They fled with £200 and a bundle of cigarettes. But police have rubbished claims that the two robberies could be connected.
Detective Constable Mark Winstanley said: "It is nonsense to say the two are linked. We can categorically state they are not. We are following a number of leads at the moment, but because of the nature of the inquiries we cannot go into greater detail.
"We can state though that it is possible a third person was involved in the post office raid and drove the car. However, we would still ask anyone who has information about either of the jobs to contact us."
