An investigation into a phoned-in bomb threat at the Mall at Rockingham Park led coincidentally to the arrest of an Apple Store employee who allegedly stole a set of speakers valued at $100.

On April 5, police said they found the speakers inside a suspicious- looking box near a large trash bin outside the building after an unknown man called 911 from a mall pay phone at about 3:30 p.m., told operators that there was a bomb, then hung up.

Though the area was secured and both the Salem Fire Department and a bomb-sniffing dog from the New Hampshire State Police Bomb Squad were called in, officers were able to quickly determine that the box did not contain explosives, according to the police.

Police arrested Bryan Donovan, 20, of Derry after a subsequent investigation led officers to believe Donovan had placed the speakers outside and planned to pick them up when his shift ended.

Donovan was charged with theft and released on personal recognizance pending his arraignment at Salem District Court.

Officials said the bomb threat was called in from a bank of payphones that is used regularly to make prank phone calls. Authorities are asking that anyone with more information regarding the prank bomb threat to call the Salem Police Department at 893-1911.
