Portland police are looking for information about a man who tried to rob with a Taser over the weekend.

A 27-year-old woman was walking on West Street near Carleton at 1:40 a.m. when a man confronted her and demanded her purse, police said.

The woman pushed the man away and he attempted to use the stun gun on her but the weapon’s fixed probes did not contact her skin as is required for that type to function.

The man ran away without the purse. He is described as white, about 5-foot-10, of average build with a shaved head, and wearing a gray hooded sweatshirt, white T-shirt and shorts.

Police ask that anyone with information call 874-8533.
