"The detention and preliminary hearing for David Coleman Headley that was scheduled for Friday in US District Court in Chicago is cancelled and will not be held (as scheduled). There is no new date and no further information available at this time," US Attorneys Office, Northern District of Illinois, announced in Chicago on Monday.
Headley's hearing was scheduled before US Magistrate Judge Arlander Keys. His lawyer John Theis was not available immediately for comment.
The attorney's office further said the detention hearing for Tahawwur Hussain Rana, also in custody on similar terror charges, would proceed as per schedule on December 2 before Magistrate Judge Nan Nolan.
Rana and Headley, arrested by the FBI in October on charges they were plotting terror attacks in Denmark and India, are also under investigation for possible links to the 26/11 terror strikes in Mumbai last year that killed 166 people.
