Two military school cadets admitted donning rented police uniforms to hold up an armored car, then escaping with $4.5 million in a heist planned by the father of one of the cadets, authorities said.

The Virginia Military Institute cadets were arrested Wednesday on campus.Also arrested Wednesday was Robert J. Jasinski, 51, of Boonton, who worked as a part-time driver for the Coin Depot Armored Car Corp. of Elizabeth.

His son, William T. Jasinski, 22, and Bryan Smals, 21, of Columbus, Ohio, rented police uniforms from a costume store while on their Christmas vacation and held up the armored car, said John McGinley, head of the FBI's Newark office.

McGinley told a news conference that the elder Jasinski met the hijacked armored car in a rented van, to which the money was transferred. Most of the money was recovered.
