Army spokesman Col. Patrick R. Seiber announced Friday that Maj. Gen. Wayne Grigsby has been suspended as commander of the 1st Infantry Division at the Kansas base. He declined further comment. An Army spokeswoman also declined to disclose the nature of the investigation.
About 17,000 troops are stationed at Fort Riley. Grigsby assumed command of the base in August 2015, after 31 years of military service that included a stint as commander of the Combined Joint Task Force in East Africa.
Grigsby was previously stationed at Fort Leavenworth in Kansas and served in multiple deployments to Iraq, including as commander of the 1st Infantry Division’s G3 unit.
Brigadier General Pat Frank, deputy commanding general, will be acting commander of the 1st Infantry Division while the investigation is underway.
