Traffic agent posing as NYPD cop busted by Brooklyn prostitute who kept evidence after being coerced into performing oral sex BY John Annese, Kerry Burke NEW YORK DAILY NEWS Monday, March 21, 2016, 10:44 PM Isaiah Delvalle, 27, told the prostitute that either the oral sex she performed was free, or she would be arrested. It wasn't the trick he thought she was turning. A quick-thinking Brooklyn prostitute who was coerced into performing a sex act on a traffic agent kept the evidence — and brought it to the cops, police said Monday. Ticket writer Isaiah Delvalle, 27, flashed a badge and gun on Jan. 11 after the woman agreed to give him oral sex for cash, authorities said. Delvalle told the victim she could either give him a freebie or end up in cuffs, cops said. She complied, but then spat the evidence onto a piece of cardboard and handed it over to police, a criminal complaint alleges. Officials created a DNA profile. About a month later, on Feb. 16, an undercover cop followed Delvalle, chatted him up and went into a restaurant with him, according to the complaint. The undercover grabbed a straw Delvalle had used, and investigators were able to match his DNA to the Jan. 11 crime, which happened at Essex St. and Stanley Ave. in East New York, according to the complaint. Delvalle had earlier used the same scheme on a another prostitute on Pine St. and Wortman Ave., also in East New York, according to the complaint. That incident happened sometime between Oct. 15 and Nov. 23, according to the complaint. Delvalle asked the woman if he could pay for oral sex, and when she agreed, he revealed a badge hanging from a chain around his neck, prosecutors said. Delvalle is charged with criminal impersonation because he’s a traffic enforcement agent, not a police officer. He told her she’d be arrested if she didn’t perform oral sex on him, and she complied, prosecutors said. Reached at his home Monday, Delvalle denied the accusations. “No, none of that is true,” he said. “Those girls are crazy. This is what they do when they don’t get what they want.” Delvalle was arrested Friday and charged with criminal sexual act, criminal impersonation, sexual misconduct, sexual abuse and coercion. The NYPD announced his arrest Monday afternoon. He’s charged with criminal impersonation because he’s a traffic enforcement agent, not a police officer, according to the complaint. He was arraigned in Brooklyn Criminal Court Saturday and released on $10,000 bail.
