Multiple firearms, including an assault rifle and three defaced “ghost guns,” were seized from an East Bloomfield Street apartment in Rome on Saturday, according to the Rome Police Department.

Police said Andre K. Ferrier, 30, negligently discharged one of the guns while inside his apartment at 12:46 p.m. Police said the round traveled through the wall into a neighboring apartment. No one was hurt.

When police searched Ferrier’s apartment and vehicle, they said they found three handguns without serial numbers — commonly referred to as “ghost guns,” an assault rifle, a shotgun, several parts to make more ghost guns, gunsmith’s tools, several magazines and a variety of ammunition. All of this material was seized.

Police said Ferrier owned the weapons in violation of a prior order of protection.

Ferrier is charged with four counts each of criminal possession of a firearm and third-degree possession of a weapon, as well as one count each of second-degree contempt and second-degree reckless endangerment, police stated.

He is scheduled to appear in court.
