An 18-year-old man was robbed in a play area in Marsh Farm yesterday (December 19).
The victim and his friend, 17, were in the Purley Centre when they were approached and threatened by two men at 11.30pm.
Both friends ran away in different directions but one slipped on the wet grass and was confronted by both offenders. They threatened him with a knife, kicked him several times, and then stole his iPhone and bag.
Both offenders are described as black and about 18 years old.
Call Beds Police on 101 with information.
