A vulnerable woman’s handbag was stolen from her in Weston-super-Mare during the middle of the day over the weekend.
The woman was targeted by a man on a bike on Saturday afternoon.
An Avon and Somerset Constabulary spokesman said: "A man cycled up behind the woman, who walks with a stick.
"He grabbed her bag and rode off towards Mendip Road.
"He was black, of large build and wore a white baseball cap."
The incident happened at between 12.40pm and 12.50pm in a lane between Locking Road and Sandford Road.
Anyone with information about the crime is asked to get in contact with police.
The spokesman added: "There may have been a second cyclist in the area at the time. We'd like to hear from that person."
