FONTANA (KTLA) -- Police say they have arrested the so-called "Granny Bandit" who has robbed at least four shoppers at gunpoint in less than a week.

The suspect has been identified as 51-year old Dodi Wasbotten.

The latest attack was reported Wednesday morning outside a Target store off Summit Avenue.

A woman with a young child told police that the suspect stole her purse at gunpoint.

The woman was shaken but no injuries were reported.

Police say the "Granny Bandit" also struck Wednesday morning outside a Wal-Mart not far from police headquarters and around 9:30 p.m. Tuesday at a Target parking lot across town.

In the first attack, the victim claims she was at the Kohl's at 14960 Summit Avenue around 11 p.m. Sunday when she was approached by the suspect.

As she walked to her car, the suspect came at her with a semi-automatic weapon and demanded her purse.

Anyone with information is asked to call detectives at 909-350-7740.
