A Queens police officer has been convicted of propositioning a pair of women, who were really undercover detectives, offering to pay them for sex, according to the Queens district attorney's office.

The NYPD officer, 39-year-old Luis Gutierrez, first approached a dancer -- and undercover detective -- while on duty on Feb. 27, 2013. He offered her money in exchange for sex, according to the DA's office.

The next day, Gutierrez spoke on the phone to a second undercover detective, who was posing as a 16-year-old girl. He also propositioned her, according to the DA's office.

"The defendant was a trusted member of the New York City Police Department," Queens District Attorney Richard Brown said in a statement. "He was supposed to uphold the law, but instead was caught -- while on duty -- offering money to a woman for sexual favors."

Gutierrez was convicted on Monday after a four-day trial of official misconduct, patronizing a prostitute, and conspiracy.

Sentencing is scheduled for September 21. He faces up to a year in jail.
