MERRILLVILLE, Ind. (AP) — A northwestern Indiana police officer faces federal charges of drug trafficking and illegally buying a gun for someone else.

Federal agents arrested Gary officer David Finley on Tuesday outside a bar a few blocks from his Merrillville home.

FBI supervisory agent Bob Ramsey tells the Post-Tribune that agents sent an informant to buy cocaine from the 31-year-old Finley during their investigation and acted quickly in the case.

Gary Police Chief Wade Ingram tells The Times of Munster he is saddened by Finley's arrest. Ingram says Finley was on vacation when he was arrested and had recently been assigned to administrative duties.

A federal magistrate ordered that Finley remain jailed until a detention hearing on Friday. It wasn't immediately clear whether he has a defense attorney.
