A search is getting underway to replace Wathena, Kansas Police Chief Brian Walker, who resigned Monday night.

City Clerk Jim Richardson confirms that Walker submitted his resignation during the City Council meeting Monday night. Richardson says the council will begin the search for his replacement with a formal advertisement expected soon.

“They’re still putting that together,” Richardson said.

Meanwhile, Raymond Hall continues his duties as acting chief.

Walker was suspended as chief in June, after 13 years in the post, for what was described as a “personnel issue.” The Kansas Attorney General’s Office conducted an investigation but concluded there was not enough evidence to charge Walker with any crime.

Officials have not commented in detail on the nature of the “personnel issue” involved.
