CHICAGO, march. 23 (UPI) -- A man who panicked out of embarrassment when asked about a suspicious object in his luggage at Chicago's O'Hare airport and said "bomb" could go to jail.

Mardin Azad Amin made a preliminary appearance in court Wednesday, charged with felony disorderly conduct as a result of the Aug. 16 incident in which he was too embarrassed to tell airport screeners the suspicious object was part of a penis pump.

Twice when asked to identify the grenade-shaped device on the X-ray screen, Amin replied "a bomb," the Chicago Sun-Times reported Wednesday.

The 29-year-old Amin later told investigators his mother was standing nearby and he didn't want her to hear what it really was, the report said.

The charge carries a possible prison sentence of three years, prosecutors said.
