Police say three molotov cocktails were thrown at a building on Larkin St. early in morning.
18-year-old Jake Hesseltine of Old Town and 22-year-old Dwayne Bell of Bangor have been arrested and charged in the crime.
Monday night, police responded to a fight in front of that same building where they recovered weapons including baseball bats and brass knuckles.
One man was sent to the hospital with a broken jaw.
Bangor police continue to investigate these cases.
