A teen was arrested and charged with menacing, criminal impersonation and drug possession, among other charges, after police said he flashed a gold badge and a black handgun during a road-rage incident Monday afternoon in Elmont, telling two occupants of another car, "I'm a cop, and I'll give you tickets."

Andrew Schreier, 19, of 87 Covert Ave., Elmont, was arrested by Nassau County police after the two victims -- a 29-year-old man and his 47-year-old cousin -- followed Schreier to a dead-end street bordering Maimonides Cemetery, calling 911 along the way, police said in a Tuesday morning news release.

Schreier fled into a backyard but residents alerted police who arrested Schreier.

Police said he was found to be carrying a forged Department of Homeland Security photo identification card and two Federation of Postal Police photo IDs.

Officers also found a small glass bottle in his right shoe containing what police called "a substance believed to be MDMA," a methamphetamine derivative. According to the complaint against Schreier, he told police that he was selling it for someone: "He told me to drop it off, take the money from the guy, and take $125.00 for myself out of the money."

Schreier was charged with two counts of third-degree criminal possession of a controlled substance, three counts of second-degree forgery, first-degree criminal impersonation, two counts of second-degree menacing and fourth-degree possession of a dangerous weapon.

At arraignment Tuesday, his bail was set at $50,000 bond or $25,000 cash. His next court date is April 12.

Police said the initial incident occurred about 3 p.m. on Elmont Road, where Schreier was involved in "a road-rage incident" with another driver.

During that incident, police said Schreier, with his window rolled down, displayed the badge and told the two occupants of the other car he'd ticket them because he was a cop.

Police said Schreier then displayed a black handgun, pointing it at the victims. The gun later turned out to be a BB gun, police said in court papers.

Police said that as Schreier drove off following the incident the victims followed him, calling 911. The two followed Schreier to a dead end on Rockmart Avenue, where police said Schreier ran from his car into the backyard of a home.

Local residents then directed police to Schreier.

Police said that in addition to the fake police IDs, Schreier also was in possession of a forged New Jersey driver's license when he was arrested.
