Two NYPD detectives were arraigned Monday on charges of raping a young woman in their custody.

Detectives Eddie Martins and Richard Hall face charges of rape, kidnapping and official misconduct as part of a 50-count indictment unsealed Monday.

The alleged incident happened Sept. 15, when the Brooklyn South narcotics detectives pulled over the 18-year-old woman in a Gravesend park. According to court documents, the detectives found marijuana and took the woman into custody. After driving off, they allegedly asked her what she would do to avoid an arrest, and defense lawyers say she consented to quid-pro-quo sexual acts.

As Hall drove, prosecutors say Martins forced the woman to perform a lewd sex act before raping her. The two allegedly switched place in a parking lot, with Hall forcing her to perform a sex act.

Friends later took the woman to Maimonides Medical Center, where a rape kit allegedly tested positive for the detectives' DNA.

The detectives are due back in court Jan. 18. If convicted, they each face up to 25 years in prison.
