Police are appealing for witnesses to a robbery at Jessops in Swan Walk, Horsham.
Three men with their faces covered by hooded tops entered the shop at about 5pm on Wednesday, June 25, and threatened to hurt the staff who tried to stop them taking cameras off the shelves.
Cameras worth more than £8,000 were stolen before the men ran from the shop and towards Horsham Park.
The first man was black and was wearing a black hooded top, white trainers and dark trousers.
The second was dark skinned, possibly Asian. He was wearing a dark hooded top, dark trousers and white trainers.
The third was white and was wearing a white hooded top, jeans and white trainers.
Sergeant Ben Websdale said: “The men ran through the town centre towards Horsham Park at a time when lots of people would have been on their way home so there could be plenty of people who saw them escaping.
“We need to speak to anyone who saw the men or who recognises their descriptions. If you saw or heard any part of the incident or have any idea where the men could be, please contact us.
“I would also urge anyone who is offered the chance to buy an expensive camera at a bargain price to get in touch with us. The thieves may try to sell them off cheaply but if we seize one of the cameras from you, you will not get it or your money back.”
