A career criminal who once tried to shoot a New York police officer in the head was charged with impersonating a Drug Enforcement Agency special agent to rob drug dealers around the city, law enforcement officials said.

A joint task force of DEA agents and city and state police officers arrested Anthony Clanton, 34, on Tuesday at his apartment at 755 Narrows Road in Staten Island.

Investigators found several counterfeit documents, including a DEA badge, a billfold with DEA credentials, two search warrants, and a Metropolitan Transportation Authority parking permit in his home, officials said. The task force also found 124 grams of crack cocaine, three handguns, 500 rounds of ammunition, a police scanner, a bulletproof vest, handcuffs, and drug paraphernalia.

On Wednesday, Clanton was arraigned on charges of burglary, criminal possession of a weapon, conspiracy, and possession of a controlled substance, according to a complaint filed in the Special Narcotics Court in Manhattan. He is being held without bail.

The first court date after the arraignment is Friday.

Clanton’s attorney, Xavier Donaldson, declined to respond to the charges. “We’re very interested in hearing the prosecutors’ evidence against my client,” he said.

Clanton was charged with an armed robbery on January 8, but officials said they were investigating a series of other robberies he may have committed.

Clanton kicked down the door to an apartment in Queens belonging to one victim, Denise Matos, after saying, “I am a DEA agent,” and showing a false search warrant, according to the complaint and officials. He then raided the home, making off with $4,000 and jewelry.

It appears as though Clanton was an adept counterfeiter who likely generated the false documents on his personal computer, officials said.

“The shield could have fooled a DEA agent, which is scary because of the access he could have gained,” the head special agent of the New York office of the Drug Enforcement Agency, John Gilbride, said.

Clanton was arrested in 1997 for attempting to shoot an undercover police officer in the head, police said. The officer, whose name was not released because he works undercover, was heard on a wiretap pleading for his life before Clanton pulled the trigger three times, police said. The gun malfunctioned and the officer was not injured.

After serving 97 months in prison, Clanton was released in 2005, police said.

Clanton enjoyed an extravagant lifestyle after getting out of prison, Mr. Gilbride said.

“He had all the toys,” he said.

Each room of his Staten Island apartment was outfitted with a plasma screen television, and a $10,000 Rolex watch was found in his bedroom. He also owned four cars: an Infiniti, an Acura, a Mercedes-Benz, and a Range Rover. One of the cars had a license place that read “HATED.”

It appears that Clanton was planning another robbery, according to the court complaint. A DEA agent observed Clanton carrying out “what appeared to be surveillance” in the vicinity of 419 64th St. in Brooklyn. That address was found on one of the phony search warrants in Clanton’s home.
