MONROE, La. (AP) — A former Monroe K-9 officer accused of theft and drug possession has been arrested.

The News-Star reports 40-year-old Kenneth Johnson was booked into Ouachita Correctional Center Monday on charges of possession of methamphetamine, theft and malfeasance.

According to an arrest warrant, Johnson had at least 36 grams of methamphetamine in his possession. The narcotics were intended to be used as a K-9 training aid.

At a news conference last week, Chief Quentin Holmes said Johnson had resigned from his position with the department and was the subject of a criminal investigation.

It was unclear whether Johnson has an attorney.
