Officer Chris Kiszka called for a Bergen County Sheriff's K-9 Unit after stopping Lamont House, 31, for multiple motor vehicle violations on West Passaic around 10:30 a.m. Feb. 19, Lt. James DePreta said.
A positive indication prompted a search that turned up a Hi-Point Arms .380-caliber handgun in the trunk, the lieutenant said.
House was charged with various weapons offenses, including having a firearm in his possession as a convicted felon, said DePreta, who assisted in the stop with Officer Hasan Shah.
He was sent to the Bergen County Jail to await a first appearance in Central Judicial Court in Hackensack.
The gun, meanwhile, was sent to New Jersey State Police for ballistics testing to determine whether it might have been used in a crime.
