Authorities late Monday night arrested a suspect in the botched plot to bomb Times Square.

Faisal Shahzad, a Pakistani-American who recently returned from a trip to his home country, was nabbed at Kennedy Airport.

"Mr. Shahzad, an American citizen, was taken into custody at JFK Airport in New York as he attempted to board a flight to Dubai," Attorney General Eric Holder said in an early-morning news conference.

"This investigation is ongoing, as are our attempts to gather useful intelligence, and we continue to pursue a number of leads," the Queens-born Holder said.

"But it's clear that the intent behind this terrorist act was to kill Americans," he told reporters.

The Customs and Border Protection agents at Terminal 4 had Shahzad's name and photo, a source told the Daily News.

"He was looking to get out of the country," a source told The News.

Shahzad, 30, of Connecticut, bought his mobile weapon of mass destruction on craigslist - and paid a 19-year-old college student $1,300 cash for it.

He is believed to have links to international terrorists and was already under surveillance for two days when the feds moved in.

They had hoped he would lead them to other possible suspects but scooped him up at JFK when he looked ready to run.

Shahzad bought the 1993 Nissan Pathfinder that he left in Times Square last Saturday night two weeks ago in a deal without paperwork, sources said.The National Security Agency had also been tracking his cell phone calls, some of which had been made to overseas numbers.

The SUV was packed with enough fuel, fertilizer and explosives to ignite a massive fireball - and kill scores of people.

In Times Square, New Yorkers and tourists alike were thrilled to hear today that Shahzad was now in the hands of the law.

"They did a great job getting this guy so fast," said Diana Suliz, 22, a bartender from the Bronx. "I feel safer now that they've got him."

But she's still worried about the future.

"I'm scared now that this might be part of a bigger terrorism threat. I have a daughter, she's only 9 months old," she said. "I don't want her to have to grow up worrying about terrorists in her own city."

Holder assured New York - and the nation - that law enforcement officials are on the case.

"This investigation is ongoing, it is multifaceted, and it is aggressive," he said. "As we move forward, we will focus on not just holding those responsible for it accountable."

Sources told The News early Tuesday that the feds are tracking three associates who may have helped the suspect.
