WESTBROOK — Two Westbrook firefighters, including one with a 1983 felony robbery conviction, were arrested last week and placed on administrative leave. Another fireman who is accused of harassing a Portland social worker was suspended.

Richard Dorr, a call firefighter, was placed on unpaid leave after his arrest on June 22. Dorr faces charges of domestic violence, criminal threatening, and obstructing the report of a crime. He is also named in a protection from harassment order obtained by his wife.

In the process of serving Dorr with paperwork, police learned that his roommate, James Gammon, a full-time firefighter, had weapons in his possession. Gammon was arrested on June 25 and charged with possession of a firearm by a prohibited person.

Gammon has a 1983 felony conviction for robbery, according to records at the state Bureau of Investigation. Gammon was placed on paid leave after his arrest.

In an apparently unrelated incident, James Harbaugh, a part-time firefighter, was placed on unpaid leave after a woman who works with his wife obtained a protection from harassment order against him. The woman, a social worker, contends in the order that Harbaugh threatened her.

The arrests come as the Fire and Rescue Department works to improve its public image in the wake of a sexual harassment problem that led to dismissals and other disciplinary actions against several department members.

Fire Chief Michael Pardue and City Manager Jerre Bryant declined to comment on the recent arrests and disciplinary measures.
