An ex-NYPD sergeant has copped to running drugs for the Nine Trey Bloods gang, court papers show.

Former cop Arlicia Robinson accepted a plea deal Nov. 27 — admitting she transported more than 100 grams of smack from the Bronx to Manhattan on July 25 last year, according to documents filed in federal court.

The transcript of the hearing was removed from the public record.

Robinson was indicted on Nov. 19, 2018, on three narcotics counts.

Tekashi 6ix9ine was a notorious Nine Trey Bloods gang member until he flipped.

Tekashi 6ix9ine, whose real name is Daniel Hernandez, is expected to be sentenced this week for his involvement in the Nine Trey Gangsta Bloods and several shootings in 2017 and 2018.

Prosecutors have asked for leniency.

Robinson is back in court in March to face sentencing.
