A Boston firefighter who participated in a bodybuilding contest after claiming he was permanently disabled has been charged with fraud in connection with his application for an accidental disability pension.

The U.S. Attorney's office announced on Wednesday that 47-year-old Albert Arroyo has been indicted on a federal mail fraud charge.

A second former Boston firefighter, 65-year-old James Famolare, was also indicted for seeking an allegedly fraudulent disability pension.

A fire department clerk, 31-year-old Erika Boylan, faces charges of perjury and obstruction of a grand jury investigation in connection with the cases.

Arroyo participated in the bodybuilding competition a few weeks after claiming in his application that he was left permanently disabled after slipping on a staircase in March 2008.
