MADISON, Wis. (AP) -

Staff logs from Wisconsin's troubled youth prison show nearly 500 incidents of aggression, fighting and violence in the four months preceding a December raid at the facility in northern Wisconsin.

The logs were provided to the Wisconsin State Journal by the Department of Corrections under the state's open records law. The reports show conditions at the Lincoln Hills School for Boys and the Copper Lake School for Girls in Irma just before federal and state law enforcement officials arrived to investigate allegations of abuse by staff members.

The documents show altercations and confrontations that resulted in 32 injuries to inmates and seven injured staff between July and December of 2015.

Troy Bauch was the union representative at the time and says the prison was getting more violent and out of control.
