Shahzad reportedly told interrogators that if he succeeded in his plot, he wanted to strike four other high-profile sites: Rockefeller Plaza, Grand Central Terminal, the World Financial Center across from Ground Zero and the Connecticut headquarters of defense contractor Sikorsky, which manufactures U.S. military helicopters, including the Black Hawk.
Shahzad also reportedly said he had a backup date for his bombing, May 8, and admitted to using online video streams to study traffic patterns in Times Square to pick the time when he would kill as many people as possible, MyFox said.
But as information from the interrogation continues to flow to media outlets, one prominent New York defence attorney is challenging Shahzad's detention, the AP reported.
In a letter to a chief judge, lawyer Ron Kuby reportedly accused authorities of violating Shahzad's rights by "squeezing information'' out of him in secret.
Kuby is not representing Shahzad, who voluntarily waived his right to a speedy trial and has been co-operating with investigators.
But Kuby argued that it is impossible to know whether or not Shahzad's rights are being protected during the interrogation.
Shahzad has been in custody since his arrest May 3 at Newark Airport in connection with the failed plot.
