Detectives have issued a fresh appeal for information about an armed robbery at Ladbrokes in Islingword Road, Brighton, just over two months ago.
Detective Constable Scott Moore said: “This was a very frightening and traumatic experience for the staff, who had a gun pointed at them.
“I would ask anyone who has information or think they know who the suspects are to please contact the police.
“In particular, we would really like to hear from two people who we believe may have some important information about the suspects.
“One of these people went into Ladbrokes a few days after the incident and gave some information about one of the suspects to a member of staff, the other person called Crimestoppers.
On Monday 29 November two men entered the bookies in Islingwood Road at about 8pm and threatened two staff members with a gun.
The staff handed over about £170 in cash.
There were no injuries to the staff or members of the public who were in the bookies at the time.
One suspect was described as white, in his thirties and 5ft 6in tall. He spoke with a local accent.
He was wearing a black hooded top which was zipped up over his mouth and a black hat.
The other suspect, was described as white, in his mid twenties and 5ft 9in to 5ft 11in tall. He spoke with a local accent.
He was wearing a grey hooded top with the hood up and a dark scarf over his face, light blue jeans and white trainers.
He was holding what looked like a black gun.
Anyone with information about the incident is asked to contact Sussex Police on 0845 6070999 or the independent charity Crimestoppers anonymously on 0800 555111.
