    Prosecutors say they've identified a suspect in the bomb threat that forced a New Jersey college campus to evacuate last week

    Dennis Mamrosz, 24, is accused of emailing a threat about Seton Hall University in South Orange, N.J. to police last Thursday. The campus was evacuated and shut down for hours as police conducted a sweep for possible explosives. 

    No evidence of a bomb was found anywhere, prosecutors said. 

    Mamrosz, a former student at Seton Hall and a Yonkers, N.Y. resident, is currently in Westchester County Jail on unrelated charges, according to prosecutors. He was not incarcerated when he made the threat last week.

    Mamrosz attended Seton Hall until 2010 and did not graduate, according to prosecutors. A motive for the threat wasn't immediately clear. 

    An arrest warrant has been issued for Mamrosz and he's expected to be extradited back to Essex County. It wasn't clear if he had an attorney.
