DOVER, N.H. -- The police chief here says two men have been arrested after a firefighter from Maine found a device resembling a bomb in his car parked at a bank.

Richard Twombly, 41, of East Wakefield, N.H., and Thomas Page, 49, of Newington, N.H., were charged with placement of simulated explosives and disorderly conduct.

Both men were arraigned in Dover District Court and released on $50,000 bail. They are scheduled for a hearing on Aug. 26.

Downtown Dover was shut down for four hours Saturday as police removed what looked like an authentic pipe bomb from the car of Patrick Gorman, who lives in South Berwick.

Officials later determined that Gorman knew the men, who work together at Gove Construction in Portsmouth, and that the incident was intended as a prank.
