According to the Providence Journal, the staff at the Nationwide Tractor Trailer Driving School in Smithfield, RI, became suspicious and contacted federal officials.

It turned out the student, Mohammed Mullawala, was in the U.S. illegally, had driver’s licenses from three states and had falsified documents to get one of the licenses.

Mullawala now faces deportation.

“Maybe he’s not a terrorist,” an official with the Rhode Island State Police told Journal. “But there’s every indication he’s hiding something.”
