The sight of an empty gun holster and an ammo box in a car in a dentist's parking lot in Gibbsboro Wednesday prompted officials to lock down two nearby schools in Voorhees for about two hours.

The lockdowns at Eastern High School and Kellman Brown Academy, a Jewish day school, were lifted after officials found the gun owner, a mechanic who works in Gloucester County, and determined there was no threat, Voorhees police and the Camden County Prosecutor's Office said.

The man, who lives in Delaware, told police he was licensed to carry a concealed firearm in Pennsylvania and Delaware and was allowed to mount the holster on the dashboard, said Voorhees Lt. Dennis Ober.

The gun owner told police he went to dentist's office on the unit block of Haddonfield-Berlin Road to pick up his girlfriend Tuesday night. The man drove the woman home in her car and planned to return to pick up the car Wednesday, police said.

Someone saw the holster, an ammo box and a duffel bag and reported it to police, prompting the precautionary lockdowns.

The ammo box contained tools and the duffel bag had clothes, Ober said.
