State police arrested two individuals late Tuesday afternoon who may be connected to the bank robberies in Arlington and Waltham earlier that day, according to a state police press release.

Trooper Mark England arrested Andrea Koutis, a 30-year-old Arlington woman, and Erik Stout, 35, of Somerville, at 4:54 p.m. after a short pursuit on Soldiers Field Road in Boston.

The two matched the description of the bank-robbery suspects given out by both Arlington and Waltham police, according to the release. They also had $7,000 in cash, the release states.

Koutis was charged with operating a stolen vehicle, failure to stop and a marked lanes violation, police said. Stout was charged with resisting arrest and disorderly conduct, according to police. Both were being held at the state police’s Brighton Barracks pending bail.

The FBI’s bank robbery task force, which includes state troopers, is currently investigating both Koutis and Stout in regards to the bank robberies, according to the release.

The East Cambridge Savings Bank at 105 Broadway in East Arlington was robbed at about 3:45 p.m. Tuesday. The Sovereign Bank at 1045 Trapelo Road in Waltham was robbed about 45 minutes later.

England spotted the twosome in a 1998 Nissan Maxima after the Watertown Police Department sent out an alert for a stolen motor vehicle matching that description. After the short pursuit, he pulled the vehicle over at the intersection of Western Avenue and Telford Street, near the Skating Club of Boston, according to police.
