Maniac outfitted with massive arsenal, including armor-piercing bullets, bashes border agent’s car in NYC

A heavily-armed driver allegedly rammed his vehicle into a border patrol agent’s car in Midtown before being chased by the agent and police — who discovered a frightening arsenal that included armor-piercing bullets, sources said.

The Friday night mayhem unfolded around 9 p.m. when the 29-year-old slammed a Dodge Durango into the off-duty U.S. Customs and Border Protection worker’s unmarked vehicle at East 36th Street and Madison Avenue near the Empire State Building, police sources said. 

The Dodge driver kept going, prompting the NYPD and the agent to give chase.

When they caught up with the motorist a few blocks away law enforcement allegedly found a scope, a handgun and extra ammo cartridges with the words “Level 3+” scrawled on it, which police believe means the ammo pierces body armor, according to the sources.

It wasn’t clear if the driver knew where the agent, who wasn’t wearing a uniform, worked.

The driver, who police believe was impaired by drugs, was in police custody facing charges Saturday.

His name is being withheld until charges are filed.

The investigation was ongoing, police sources said.
