A 21-year-old woman had her bag snatched as she walked out of Boston town centre last night (Saturday).
Police say the woman was walking along West Street towards Sleaford Road shortly before 11.30pm when the offender approached from behind, grabbed her handbag and ran off towards Asda.
Members of the public stepped in and were able to get her bag back for her.
Police now want to trace the offender, who is described as a white male with short black hair, slim build and was wearing a black and white stripe jumper and black gloves.
PC Steve Hatton would like to trace the members of the public who assisted.
Anyone with information should contact him by dialling 101 and quoting incident number 526 of March 29.
