Suspect Faisal Shahzad was arrested Monday at John F. Kennedy International Airport while authorities held back the Dubai-bound Emirates flight and brought passengers back into the waiting lounge.

Passengers arriving in Dubai said the plane left the gate and taxied for about five minutes before the pilot made an announcement that the plane was returning. They were asked to identify their carry-on luggage, but there was no other information given by the flight crew.

Some passengers said they only learned of the links to the failed Times Square attack after seeing news reports in the terminal or talking with airport security officials. It was unclear whether any passengers witnessed the arrest of Shahzad, who was placed on a “no-fly” list by U.S. officials just hours earlier.

The passengers said they went through another full security screening before returning to the plane, which was delayed about seven hours.
