Police are appealing for witnesses after an armed robbery at Durrington post office in Salvington Road, Worthing.
At 1.50 pm a ginger-haired man with thin-framed glasses and a balaclava threatened a member of staff in the post office with a pistol-type gun.
The male member of staff gave him a quantity of cash and the man left, heading towards Durrington Lane.
The man was about 6′ 3″ and aged about 20. He was wearing jeans and a dark hooded top with a green letter M on the front and back and was carrying a rucksack.
Detective Inspector Andy Westwood said: “We are appealing for anyone who recognises the description of the man or who saw someone acting suspiciously outside the post office or in Franklin Road before the robbery to contact us.
“The post office worker was not hurt but understandably has been left very shaken by what happened.
“Please contact us if you saw or heard anything that could help us with the investigation.”
Anyone with information should call 101 quoting serial 739 of May 9th, email: email@example.com or the independent charity Crimestoppers anonymously on 0800 555111.
