WEST TISBURY, MASS. (WHDH) - An arrest has been made in connection with the robbery of a Rockland Trust Bank on Martha’s Vineyard earlier this week, officials announced Saturday.

Cape & Islands Assistant District Attorney Tara Miltimore confirmed the arrest around 4 p.m.

Officers responding to an alarm at the Rockland Trust learned that three robbers armed with handguns had jumped an employee around 8:15 a.m. as they were on their way in to open the building.

The employees were then zip-tied while the bank was robbed. One eventually managed to break free and sound an alarm, there were no reported injuries.

Police say the suspects, who were wearing dark hooded sweatshirts and old man masks, stole one of the teller’s vehicles and later dumped it on the other side of the island.

Miltimore said the investigation is active and ongoing.
