Portland police are investigating a pair of similar armed robberies that occurred downtown about 10 p.m Thursday.

A 43-year-old Portland man was walking on Cumberland Avenue near Chestnut Street when two men accosted him and demanded his wallet, with one showing a handgun, police said. The man ran.

Ten minutes later, in the same area, two women were confronted by what appears to be the same men. In that case, the 45-year-old Falmouth woman and 40-year-old Cumberland woman turned over items to the men, then fled, police said.

There were no injuries.

One robber is described as a white male in his late teens or early 20s, 5-feet-7-inches tall, thin and clean shaven. He was wearing a gray hooded sweatshirt with the hood up and a scarf covering a portion of his face, police said. The second man is described as in his 20s, 5-feet-9-inches tall and with a slightly larger build. He wore a dark sweatshirt with the hood up and a dark scarf covering his face so the victims could not be sure of his skin color.

Anyone with information is asked to contact Portland police at 874-8575.
