Portland police are investigating a pair of robberies that have similarities and may be connected.

On Wednesday night, a 25-year-old Portland woman was walking near 148 Clark St. at 11:40 p.m. when a man came up behind her, displayed a gun and grabbed her purse, police said.

The man was described as 5 feet 11 inches tall with a slight build, dark skin, and wearing black clothing, including a jacket, and a scarf. The man was last seen running down Clark Street, police said.

The robbery was similar to one that happened at 11 p.m. Friday. A 56-year-old Falmouth woman was walking with another woman on Congress Street near Lincoln Park when a man grabbed her purse and threatened her with a gun. The woman struggled briefly until she realized the man had a gun, police said.

The man ran away and was seen getting into an older four-door Mercedes-Benz.

The woman described her attacker as between 5 feet 7 inches and 6 feet tall, with a dark complexion and scruffy facial hair.

Police say the crimes are similar but they cannot say for sure they are connected.

Anyone with information about the incidents is asked to call police at 874-8575.
