LOUISVILLE, Ky. (WDRB) -- The head of a specialized Louisville police unit is off the job Thursday morning. It's a story that's still developing, and Louisville Metro Police is being very quiet about it.

All we know at this time is that the head of the VIPER Unit, Lt. Kit Steimle, is on administrative reassignment.

Steimle was the Commander of the team brought together in 2012 to go after Louisville's most dangerous criminals. LMPD officials confirm that he is now the subject of a "professional standards investigation."

Leaders will not say anything about the nature of the case, or why Steimle was removed from the unit. They did tell us that Steimle is currently working in an administrative capacity within the department, and not leading another team.

The VIPER Unit was highly touted when it formed. Steimle recently sat down with WDRB to talk about its success.

"These offenders are the most violent in the city, and they need to be taken off the street as soon as possible," Steimle recently said. "Our fugitive squad is fantastic at finding people."

We're told The VIPER Unit continues to work under the leadership of Lt. Sean Jackman.

WDRB is looking into whether any of the criminal cases against the fugitives the VIPER Unit captured under Steimle's command will be affected.
