MINEOLA, N.Y. (AP) -- A New York man who allegedly posed as a federal air marshal after being pulled over with an assault weapon, ammunition and body armor in his car has been charged in a 51-count grand jury indictment.
Investigators say he produced a fake shield and credential when he was stopped on Dec. 3.
Prosecutors say Mark Vicars also allegedly had another 8,300 rounds of ammunition and other weapons in his Syosset home.
Vicars pleaded not guilty Tuesday to weapons possession, criminal impersonation and other charges.
Acting Supreme Court Justice Meryl Berkowitz set bail at $750,000 or $500,000 bond.
Vicars could face up to 15 years in prison if convicted of the most serious charges. His attorney did not immediately return a call for comment.
