Faisal Shahzad, an American citizen who is originally from Pakistan, has been arrested in connection with the failed car-bomb attack in New York City on Saturday evening.
US Attorney General Eric Holder said Mr. Shahzad was held at John F Kennedy Airport in New York on Monday as he attempted to leave for Dubai.
Mr. Holder also said, "This investigation is ongoing, as are our attempts to gather useful intelligence, and we continue to pursue a number of leads."
He added: "We will not rest until we have brought everyone responsible to justice."
Police said that they had tracked down the registered owner of the dark, 1993 Nissan Pathfinder that contained the crude home-made bomb but he was not a suspect. He sold his car three weeks ago to a man described as of Hispanic or Middle Eastern appearance, aged about 30 which is now claimed to be Faisal Shahzad.
Pakistan Foreign Minister Shah Mahmud Qureshi said on Tuesday that Pakistan will provide full cooperation to the United States over New York bomb plot.
The senior Pakistani government official said, “Pakistan and the US have ongoing, robust cooperation on counter-terrorism. If required, we will extend fullest cooperation to US."
