A man pushed a 62-year-old woman to the ground before snatching her handbag in an alleyway off Toddington Road on Wednesday last week.
The victim had first seen the man as she walked through Sundon Park when he asked her the time.
Shortly after she felt a tug on her bag before the man pushed her and grabbed her bag.
The man is described as white, 5’6” to 5’8” tall, with a slim build, in his late 20s to early 30s. He wore a beige beanie hat.
Call 101 with information.
