The first suspect is described as Caucasian, early 30s to 40s with light brown hair, light brown facial hair, wearing a faded orange shirt and a grey jacket.

The second suspect is in his early 20s, thin face, light blond hair, wearing a green sweater and a blue winter jacket.

Police said an unrelated attempted carjacking occurred when a woman was approached while leaving a restaurant in the north end sometime the save evening.

The female suspect produced a knife and demanded the keys to the other woman's car, police said.

The woman gave her "a little bit of money," Maron said, and the assailant ran off.

"It's important to remember these incidents happen fairly regularly, unfortunately, and they're all not related to each other." Maron said. "We just need people to be aware of their surroundings."

Earlier this week police arrested a man in connection with a violent assault on a 46-year-old woman in which an armed suspect attempted to steal her car and purse.

Charges are pending in that incident.
