There is currently very little information beyond this, as we don’t know who the man in custody is or the motivation behind the attack.

UPDATE: Authorities are calling the suspect a “suicide bomber” after he was apprehended with wires attached to him and a pipe bomb that went off prematurely inside the Port Authority terminal. From the New York Post article:

A suicide bomber set off a device at the Port Authority bus terminal Monday morning, law enforcement sources said.

The suspected bomber – who had wires attached to him – was armed with a pipe bomb and a battery pack, sources said.

He was taken into custody after the device partially detonated inside the passageway to the N, Q and R trains, according to sources.
