The FBI filed a compliant on Tuesday, May 4 before the Court of Judge Nathaniel Fox, Southern District of New York.
In the 10-page complaint, FBI alleged that Shahzad travelled from Connecticut to New York on a sports-utility vehicle (SUV), which carried the explosive he wanted to detonate in the Times Square on Sunday, May 2.
Besides this, the terror suspect has also told the FBI that he underwent training in Pakistan's Waziristan.
“After the arrest Shahzad admitted that he had attempted to detonate a bomb in Times Square. He also admitted that he had recently received bomb-making training in Waziristan, Pakistan," the FBI said.
Shahzad, who was arrested on Monday, May 3 night at the JFK airport while he was on board a plane to Dubai, got his American citizenship in Apr 2009.
He had recently been to Pakistan and stayed there for five months. He told the immigration officials that he went to his home country to visit his parents.
“Shahzad, after receiving bomb-making training in Waziristan, Pakistan travelled to the US, transported a sports utility vehicle to the vicinity of 45th Street and Seventh Avenue in Manhattan, New York, and attempted to detonate explosive and incendiary devices located inside the sports utility vehicle," the complaint added.
