New York Police Department were reviewing more than 6,000 security cameras while they traced the suspect’s steps after an explosion happened during rush hour traffic in a crowded subway corridor close to the Port Authority Bus Terminal on Monday morning, leaving five people injured, according to CBS News.

CBS News homeland security correspondent said that police were working overtime to get a more thorough understanding of the 27-year-old suspect, Akayed Ullah, and searched his apartment building in a working-class Brooklyn neighborhood.

Sources said Ullah constructed the bomb himself and claimed that he was inspired by the Islamic State of Iraq and Syria (ISIS) to carry out the attack in the tunnel since it had a series of Christmas-based advertisements.

Neighbors in Brooklyn said the previous taxi driver and electrician was mostly a loner and would rarely speak more than a few words when they did see him.

Kisslyn Joseph, a neighbor, said she told police something from the weekend stood out to her, “The only thing that I heard was an argument that happened on Sunday morning, it was like, uh, around 2:00, 3:00 in the morning.”

The scene on Monday morning was more chaotic and was captured on security cameras and audio which said, “We got a perp down with a device in a tunnel. Central, four two and eighth. There are reports of an explosion over division.”
Ullah came to the U.S. from Bangladesh in 2011 and first lived with his parents and siblings on a family immigrant visa, eventually becoming a legal permanent resident.

Police Commissioner James O’Neill said Ulah wore an “improvised low-tech explosive device attached to his body.

The device was an improvised pipe bomb which was attached to Ullah with Velcro and zip ties, according to John Miller, NYPD deputy commissioner of intelligence and counterterrorism.

Ullah reportedly told police that he made the bomb in his home.

Investigators are still working to determine if anyone else may have known about Ullah’s plan to detonate the pipe bomb on Monday morning by searching through his electronic devices to see his online behavior and conversations.

Authorities will also scan terrorism databases to see if he was in contact with any terror groups or people associated with terror groups.

Law enforcement sources said that four Port Authority Police officers apprehended the suspect, who was surrounded by smoke and debris on the floor.

A photo from the scene taken by a bystander showed a bearded man, crumpled on the floor with most of his shirt blown off and black soot covering his bare chest while a police officer holds the man’s hands behind his back.

Ullah sustained a shrapnel wound and was taken to a Manhattan hospital.

One source said that while police approached the suspect, he seemed to reach for a cellphone and had wires poking out of his jacket and pants.

The four officers identified as making the arrest range in age from 26 to 45 years old, with three of them having former experience in the military and one was a bomb technician.

Sources said Ullah was back in Bangladesh for around a month in September and Ullah also previously visited the United Arab Emirates.
