Officials at a Kansas prison say three inmates in a segregation unit tried to hang themselves simultaneously.

The incident happened Tuesday afternoon in the administrative segregation unit at Hutchinson Medical Center. Prison officials released a statement Tuesday night saying only that four inmates had suffered some kind of medical emergency.

More details, including the attempted hangings, were released Wednesday. Officials said a corrections officer made the discovery around 3 p.m. Tuesday and called for help to remove the inmates from the cell.

One inmate was treated at the prison clinic. The other two were transferred to a Wichita hospital, with one expected to be released Wednesday.

A fourth inmate was taken to the prison clinic with chest pains. He was later returned to the prison unit.
