A former firefighter in Westbrook has been indicted on a charge of possession of a firearm by a felon.

A Cumberland County grand jury indicted James Gammon, a firefighter for the Westbrook Fire and Rescue Department, who lost his job in July.

Gammon was arrested on June 25 after Westbrook police learned that he possessed firearms. State records show that Gammon has a 1983 felony conviction for robbery. He was placed on leave from the fire department after his arrest.

Westbrook Police Chief Bill Baker said Gammon’s indictment was expected.

“The facts of the case are pretty straightforward and we look forward to proceeding to trial if that’s the choice the defendant makes,” he said.

Gammon is scheduled to be arraigned in court on Nov. 18.
