The Kansas Bureau of Investigation is investigating the Kansas City, Kansas, police chief’s use of a county-owned lake house.

The Kansas City Star reports the investigation centers on whether Chief Terry Ziegler “double dipped” when he took paid time off work while also charging the county government for work he did on the lake house.

The Unified Government allowed Ziegler to pay little rent on the house on Wyandotte Lake Park if he made repairs on the property. Officials put the lease in writing after a citizen inquired about it.

Ziegler sent an email to police department employees on Monday confirming the investigation.  He will continue working during the investigation.

In December, Mayor David Alvey said he thought the arrangement with Zeigler was in the county’s best interests.
