Suspicious behavior led to the arrest in Boston of a truck-driving student. (Hat tip: instant.)

A truck-driving student is in custody in Boston after raising suspicions when he wasn’t interested in learning how to back up his rig.

WLVI-TV (Ch. 56) reported last night that the would-be trucker is a 28-year-old Muslim from India and had overstayed his visa. An investigation is under way to see whether there is any connection between his unusual behavior and a terrorism plot. Federal authorities were alerted by instructors at the Nationwide Tractor Trailer Driving School in Smithfield, R.I., WLVI reported.

The student was described as a resident of New York, with driver’s licenses from New York, New Jersey and Rhode Island.
