A gang wearing Halloween masks snatched a man’s mobile phone after a night out in Bury St Edmunds on Saturday.
It happened at around 3am on Station Hill.
The victim was walking towards the station using his iPhone 5 to make a call, when a group of four people approached him from behind and one of them grabbed the phone from his hand.
They were dressed in black and wearing Halloween masks.
