BRICK TOWNSHIP -- An Indiana man carrying an arsenal to visit his "Facebook girlfriend" in Brick Township was arrested after police found him sleeping in his car, authorities said Thursday.

While conducting a routine check of the area, township patrolmen found Antonio J. Perez, 24, of Elkhart, Ind., sleeping in his car at the Boland Field Baseball Complex on Lanes Mill Road at 12:30 a.m. on Wednesday, said Brick Detective Sgt. Henry Drew, a police spokesman.

He said further investigation by Detective Robert Shepherd revealed Perez was headed to meet his "girlfriend" whom he had met on Facebook two years earlier but had yet to meet in person.

Police found with Perez four loaded weapons, 1,000 rounds of 7.62 ammunition, a canister of pepper spray and a gas mask, he said.

The guns were a Sig Sauer P226 40-caliber handgun a Smith & Wesson .38-caliber revolver, a Smith & Wesson .357 revolver and a WASR 10, which is an AK47-style weapon, with a loaded 30-round magazine, Drew said.

Drew said police do not know the actual nature of the relationship between Perez and the woman., who lives in Brick. He said police are also unsure whether she knew if he was coming but after checking on her, they determined she was unharmed. Police believe Perez was sleeping in his car after being tired from the long drive.

Drew said the woman lives in the area of the baseball complex but investigators don't believe he was watching her.

Patrolmen Mark Nixon, Mark Catalina and Marc Alexander found him by chance when checking the area, Drew said.

Perez was charged with stalking, possession of a weapon for an unlawful purpose, possession of a rifle, possession of other weapons, possession of destructive devices and possession of certain bullets. He was also charged with two counts of possession of large capacity ammunition magazine, possession of a handgun, disposition of weapons, disposition of an assault firearm, possession of marijuana, and having an unregistered vehicle.

Bail was set by municipal court Judge Robert Lepore at $100,000 with no 10-percent option. He was being held in the Ocean County Jail in Toms River.
