NILES — A Mercer, Pa., man had his bond set at $100,000 and his case bound over to the Trumbull County grand jury after he was arrested last week after police said they found weapons and explosive devices in his vehicle.

John Podleyon pleaded not guilty to charges of possessing dangerous ordnance and carrying a concealed weapon.

During a hearing Monday in Niles Municipal Court, he waived his right to a preliminary hearing.

According to a Niles police report, an officer spotted Podleyon’s vehicle in the parking lot of the Von Isley Estate on state Route 46. When approached, Podleyon said he was lost and trying to return to Mercer, Pa. The officer noticed a box in the backseat commonly used to store firearms and asked if there were any weapons in the car.

Podleyon admitted to having a pistol and reached for it, prompting the officer to order him to stop and place his hands on the dashboard, the report states. He was then handcuffed and placed in a police cruiser.

Officers found a loaded pistol with a bullet in the chamber, another gun under the seat and what appeared to be homemade explosive devices with wires and possible switches.

The Youngstown Police Department’s bomb squad was called to the scene to safely handle and remove the suspicious items. Podleyon’s vehicle was towed and four guns were taken as evidence.
