LEWISTON – Police are searching for a woman suspected of spraying an older woman with chemical spray Thursday afternoon in a robbery outside Hannaford on Sabattus Street.

Police said that about 1:45 p.m., a woman wearing a gray knit cap approached an older lady in the parking lot, sprayed her with mace and then ran off with her purse.

Police said the suspect then ran to a small, gray car and drove away.

The elderly woman was treated for the effects of the spray and the search began for a suspect. By Friday night, no arrests had been made.

Police working with the victim and witnesses on Friday created a composite drawing of the thief. She is described as under 5 feet, 6 inches tall, and weighing 100 pounds. She is believed to be between 35 and 45 years old.

Anyone with information about the attack is asked to phone Detective Brian O’Malley at 795-9000, ext. 203, or their local police department.
