Police think The Game should stick to rap, not law enforcement.

The rapper was arrested this week after telling a cab driver that he was an undercover police officer and persuading the driver to run a series of red lights, police said Saturday.

The 26-year-old, whose real name is Jayceon Taylor, allegedly picked up a livery cab Thursday night shortly after he appeared on "Late Show with David Letterman." The cabbie drove about 13 blocks before he was pulled over, police said.

Taylor faces a charge of impersonating a police officer, said police Sgt. Kevin Hayes.

His lawyer, Jeffrey Lichtman, denied the accusation Saturday, saying police had been tailing his client throughout his stay in New York and that the cabbie was a terrible driver.

"This is really a new low even for the NYPD," Lichtman said. "It's a big joke to harass him and other members of the hip-hop community, and ultimately arresting him. Let's see how funny they think it is during the cross-examinations of this trial."

The rapper was told to appear in court on Dec. 12, Lichtman said.

A call seeking comment from the Manhattan district attorney's office was not immediately returned Saturday.
