LEAVENWORTH, Kan. (AP) - Another patient has filed a lawsuit accusing a former physician assistant at the Veteran's Administration hospital in Leavenworth of sexual abuse.

The complaint filed Tuesday in U.S. District Court of Kansas brings to at least four the number of civil lawsuits filed against Horton resident Mark Wisner and the federal government. Wisner also faces criminal charges of aggravated criminal sodomy, solicitation and sexual battery.

The hospital reiterated that once accusations were brought to the attention of its leadership Wisner was immediately removed from patient care and an investigation initiated.

The Iraq war veteran alleges that Wisner conducted improper genital examinations and comments. He contends Wisner suggested he would withhold pain medications if the patient did not allow the examinations.
