The man accused of pulling the emergency brakes on New York City subway trains over the last three months refused to answer questions as he was led away by police.

Isaiah Thompson, 23, was arrested at his Brooklyn home late on Thursday night for allegedly pulling the brakes of a northbound 2 train near 14th Street in Manhattan on Tuesday.

He's accused of causing nearly 750 delays, wreaking havoc for millions of commuters and residents.

On Friday morning, he kept his head down as video shows two police officers leading him out of an office at a Canal Street station and into a parked police vehicle.

'Why'd you do it, sir? Why'd you pull the brakes?' a man off-camera asks.

But Thompson doesn't respond and slides into the backseat of a silver vehicle, and one of the officers shuts the door.

Thompson has been charged with reckless endangerment and criminal trespassing, police said, and is being held in custody while awaiting arraignment.

According to the New York Post, he was also charged over an incident on May 16 incident in which he exposed himself on the subway.

On Thursday, authorities released surveillance video showing a man riding on the back of a train in Manhattan just moments before he pulled the brake, now believed to be Thompson.

In the image, the suspect is shown was wearing a Yankees baseball cap and a Nike T-shirt that had 'Swag Don't Come Cheap' printed on it.

He boarded the train at the West 14th Street subway station at 5.43pm on Tuesday via the rear car.

The man opened the rear door and rode several stops on the outside of the train car before activating the emergency brake.

The NYPD released the images of him, saying he was wanted for reckless endangerment.

Authorities have been searching for a serial suspect or suspects who have been pulling emergency brakes on subways since March.

According to incident reports obtained by Jalopnik, a total of 747 rush hour trains have been either delayed or canceled because of a similar pattern of disruptions in the last three months.

Each time the suspect activates the emergency brake, it can trigger delays for the dozens of trains waiting behind - hence the high number of reported incidents.

In each of the incidents, the emergency brakes are suddenly activated and the conductor finds the back cab door unlocked and rear train door open.

The subway brake spree is believed to have started on March 11 on an uptown 5 train leaving Grand Central.

The conductor spotted a man climbing onto the tracks after the emergency brakes had been activated.

That same man was spotted minutes later on the back of a downtown 4 train just moments before its brakes were activated near the 28th Street station.

The suspect delayed or cancelled 118 trains in a span of 36 minutes on Tuesday on the 1, 2, and 3 lines.
