A self-described “zombie enthusiast” was busted at the Port Authority Bus Terminal in possession of swords, knives, burglar tools, night-vision goggles and hand-drawn blueprints, The Post has learned.

Christopher Rodger, 25, first drew the attention of two PA cops Tuesday when he was spotted wearing a trench coat on a warm night, and had an “empty” look in his eyes, sources said.

PA Officers Thomas Kemble and Leonard Trubia grew even more suspicious when they spotted the long camouflage bag Rodger had slung over his shoulder.

When the cops questioned him, Rodger blurted that he was carrying a gas-powered pellet gun. That prompted a search which also turned up five samurai swords, three daggers and other knives, police said.
