Two friends had their mobile phones stolen by a gang while they were sitting in the Racecourse park in Northampton in the early hours of the morning.
The two had left the town centre sometime between 2am and 4am on Saturday April 26 and decided to sit on a bench in the park, listening to music on their mobile phones.
They were then approached by a gang of three men, who demanded that they hand over the phones.
The robbery happened in a playground close to the Colwyn Road area of the Racecourse.
Two of the men where white and aged between 25 and 30. They both wore black hooded tops with the hoods up and dark tracksuit bottoms.
