INDIANAPOLIS, Ind. (Jan. 13, 2016) -- Indianapolis police are investigating one of their own.

An IMPD officer is one of three people facing possible criminal charges of dealing cocaine.

Christopher Reed, 33, Veronica Purdy, 41, and Nikolas Layton, 35, face preliminary charges including suspicion of dealing in cocaine, conspiracy to deal cocaine, dealing in a controlled substance and possession of cocaine.

The trio were arrested Tuesday night.

The police officer arrested is also the son of the Marion county sheriff.

From the moment he got sworn into office, Marion county sheriff John Layton has vowed to uphold the law.

That’s why Layton expressed sorrow that his son, Nikolas Layton, a 10-year-veteran of the IMPD may have broken that vow.

The criminal drug investigation dates back to November, when Nikolas Layton and two other suspects are accused of distributing narcotics, specifically cocaine, over several days.

The younger Layton was able to post bond and has been released from jail.

Before his arrest, Layton worked with IMPD’s hit and run investigation unit and was suspended without pay.

Sheriff John Layton issued the following statement:

This is obviously a heart breaking moment as a parent, especially as a parent who is also the Sheriff, and even more as the father of a police officer. I have never tolerated this kind of alleged behavior in law enforcement. I have full faith in the criminal justice system, and I feel certain that justice will be done.

No one with the police department would talk about the case on camera.

Layton is due in court Thursday morning.
