Just hours after a backpack containing five explosives was found outside the main train station in Elizabeth, New Jersey late Sunday night, FBI agents and the FBI’s Evidence Response Team is at an address in the town this morning.

NBC’s Tom Winter, who has been reporting on the development out of Elizabeth since Sunday evening, took to Twitter shortly ago with the following updates into the investigation:

On Sunday night at about 9:30 p.m. local time, two men found a package inside of a garbage at the street intersection closest to the Elizabeth train station, a primary thoroughfare for train travel between New York City and Trenton. Train service on New Jersey Transit’s Northeast Corridor was suspended throughout the night, as a bomb robot was dispatched to deal with the package after the men dropped it, realizing it was wired. Shortly after 1 a.m. local time, one of the explosive devices inside the backpack was detonated, though it was not through a controlled detonation by authorities.
