Details have emerged of how the suspect in the attempted bombing of New York's Times Square was arrested just minutes before leaving the country.

纽约时代广场爆炸未遂案的嫌疑人正要离开美国的时候遭到逮捕，日前此案的一些细节已经浮现。

Police traced Mr Shahzad through the car's ID number and phone records

According to court papers, Mr Shahzad has admitted his role in Saturday's attempted attack and said he received training in bomb-making in Pakistan.

The Pakistan-born US citizen has been charged with terrorism-related crimes.

These include attempting to use a weapon of mass destruction（大规模杀伤性武器） and transporting an explosive device with the intent to kill.

"It is clear that this was a terrorist plot aimed at murdering Americans in one of the busiest places in the country," said Attorney General Eric Holder¹.

Mr Shahzad did not appear before a judge on Tuesday as expected to hear the charges. No reason has been given for the delay.

He is alleged²（断言，宣称） to have bought an SUV that was found loaded with an improvised³ bomb in Times Square.

The unexploded bomb left crucial evidence intact（完整的，原封不动的） that detectives used to trace Mr Shahzad, including the vehicle's identity number.

With that number, police found the former owner who said she sold it to Mr Shahzad for cash without official paperwork being exchanged.

But the former owner had Mr Shahzad's mobile phone number and gave it to police.

The pre-paid phone had also been used to call a Pennsylvania fireworks shop, the court documents said.

Despite his name being added to the government's no-fly list earlier on Monday, Mr Shahzad managed to buy a ticket on an Emirates flight to Dubai and made it through JFK's security checks late that evening.

He booked the ticket while on his way to the airport and paid for it with cash, police said.

Customs agents checking the passenger list about 30 minutes before the plane was due to take-off realised Mr Shahzad's name was on it and stopped the flight with just minutes to spare as it taxied（滑行） to the runway.

Despite the suspect nearly managing to leave the country, Mr Holder denied he would have escaped.

"I was never in any fear that we were in danger of losing him," he said.

The car containing a bomb made from fertiliser, fireworks, petrol and propane（丙烷） gas tanks was left in Times Square on Saturday evening.

The 1993 Nissan Pathfinder（探路者，开拓者） was parked with its engine running and hazard lights（危险警告灯） flashing.

The bomb was discovered and dismantled⁴ before it could explode, after a street-vendor noticed smoke coming from the vehicle and alerted police.
