DOVER, N.H. – The police chief in Dover, N.H., said two men have been arrested after a firefighter found a device resembling a bomb in his car parked at a bank.

Police on Thursday arrested 41-year-old Richard Twombly of East Wakefield and 49-year-old Thomas Page of Newington on charges of 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 of South Berwick. Officials later determined the victim knew the men, who work together at Gove Construction in Portsmouth, and the incident was intended as a prank.
