Security investigation at BWI checkpoints causes some delays

LINTHICUM, Md. - (AP) -- Authorities say a man who falsely claimed he had a bomb inside a carry-on bag at a Maryland airport has been taken into custody.

The Maryland State Fire Marshal's office said says bomb squad technicians performed an X-ray of the bag at Baltimore/Washington International Thurgood Marshall Airport early Tuesday and saw what looked like a possible hand grenade device. Deputy State Fire Marshal Bruce Bouch said a robot was deployed and no device was found.

The fire marshal's office says 46-year-old Jason C. Hallenbeck was taken into custody with Maryland Transportation Authority Police. A Maryland Transportation Authority Police spokesman didn't immediately respond to a phone message left Tuesday.
