Four people were arrested on theft and drug trafficking charges Tuesday after a SWAT team executed a search warrant at the Maine Motel in South Portland, police said.

Officers converged on the motel, located at 606 Main St., about 5:30 p.m. in connection with an ongoing investigation by the Maine Drug Enforcement Agency, South Portland Detective Sgt. Chris Todd said in a statement.

Officers set off two flash bangs, an explosive device that creates a loud bright diversion. Three people were arrested at the motel, and a fourth was apprehended as he tried to flee in a vehicle. No shots were fired and no one was injured, police said.
