One is an US Army veteran with three combat tours.
King, who has long advocated for tough policies when it comes to surveillance in New York City and beyond, said many people could have been killed if the explosive had detonated in a subway auto.
Port Authority Police Department officers Jack Collins, Anthony Manfredini, Drew Preston and Sean Gallagher were credited with saving dozens of lives after the blast in a tunnel between the Port Authority/42nd Street subway station and the Times Square/42nd Street stop on Monday morning by jumping on the suspect in the attack, Akayed Ullah, as he reached for his cellphone.
"I am so thankful there was no loss of life and I could not be prouder of our Port Authority police officers, their actions and dedication to their sworn duty".
"These police officers are among the most highly trained police officers in the nation, as are all Port Authority police officers", said Paul Nunziato, the president of the PAPD's rank-and-file union.
Manfredini was first at the scene - a walkway linking the bus terminal to the subway system, according to Bobby Egbert, an association spokesman. Ullah and five others were injured in the blast, which triggered panic in the busy commuter hub during rush hour.
The officers responded as people ran away from the scene, which was filled with smoke and debris, Egbert said.
The officers saw wires running from the suspect's jacket to his trousers, according to Egbert. The officers were anxious he might try to detonate another device. "There was a struggle with him, they had to keep him from reaching the cell phone, obviously they had no idea what he was going to do with the cell phone".
Once Ullah was in custody, the officers began to evacuate commuters safely. Four people suffered minor injuries, the FDNY said, though it's unclear if the attacker was included among them.
The apprehending officer, Collins, was working his usual routine looking for child traffickers at the Port Authority Bus Terminal when the explosion occurred, WABC-TV reported.
Port Authority Chairman Kevin O'Toole praised the four officers.
A few injuries have been reported, so far. "Our officers responded immediately and put themselves in harm's way to protect the public".
