The Saudi national arrested after arriving at Detroit Metropolitan Airport with an altered passport and pressure cooker was unaware of the device's connection to the Boston Marathon bombing, according to his attorney.

Hussain Al Khawahir appeared in federal court in Detroit yesterday and waived his right to a detention hearing. Attorney James Howarth says there was no intention of wrongdoing on Al Khawahir's part.

Al Khawahir told agents after the flight from Amsterdam last Saturday that he was on the way to visit a nephew at the University of Toledo, but allegedly gave differing reasons for having the pressure cooker in his luggage.
