The Troy Police Department's Drug Unit has been placed on administrative leave.

At this point, it is unclear why they were placed on leave but Troy Mayor Patrick Madden confirms there is an internal investigation underway.

Mayor Madden says in a statement:

“On Thursday, June 15, all members of the Troy Police Department’s Firearms Interdiction and Narcotics Suppression (FINS) unit were placed on leave resulting from a personnel matter which involves the conduct of certain officers of the unit during a particular occasion.

An internal investigation has been commenced to protect the integrity of the Troy Police Department and reassure the public’s continued trust and confidence in our law enforcement officials."

Meanwhile, Troy's common council president is asking for answers, in a statement Carmella Mantello said:

"I am deeply concerned that this would remove from the front line of a total police department unit in our city's fight against drugs and related matters. I am calling upon the Mayor to advise the Council and the public as to how the city would fill the gap and responsibilities of this important unit."

Mantello says she doesn't believe a full police unit has ever been removed in the city’s history.
