PESOTUM, Ill. (AP) — A Minnesota man is facing drugs and weapons charges after three handguns, a rifle and nearly 2,500 rounds of ammunition were found in his vehicle in the parking lot of an Illinois State Police district headquarters.

Just after 1 p.m. Thursday, a man drove into the restricted parking area of the Illinois State Police District 10 headquarters in Pesotum, according to authorities. The driver of the vehicle was then confronted by a ISP trooper. The officer noticed that the driver had a handgun.

The driver refused to give identification to the trooper. The driver was removed from the vehicle and was arrested, police said.

After investigation, police found three handguns, a rifle, multiple magazines and approximately 2,400 rounds of ammunition.

The 38-year-old man identified as Jeffrey Heard of Pipestone, MN, has a valid Minnesota concealed carry permit.

Heard is now facing charges of possession of a firearm on state-supported property, possession of a controlled substance, and possession of cannabis.

State police do not believe Heard was targeting or intended harm to law enforcement officials.

The incident is still under investigation.
