Authorities said a deputy was injured Thursday in a scuffle with an inmate.
The Dane County Sheriff's Office said a deputy and jail staff at the Dane County Jail were attempting to move an inmate to another cell for health and safety monitoring at about 3:20 p.m.
Initially the inmate agreed to cooperate but when deputies entered the cell, the inmate began fighting, the report said.
A deputy was taken to UW Hospital and treated and released for a fractured shoulder, the sheriff's office said. The deputy may be unable to work for several weeks.
The inmate was charged with causing injury by resisting an officer, officials said. The inmate was taken to Mendota Mental Health Institute Thursday night after the scuffle and remained there Friday, according to sheriff's office spokeswoman Elise Schaffer.
Schaffer said the department did not share the inmate's name because doing so would violate privacy laws concerning personal health information.
On Nov. 19 Sheriff Dave Mahoney told News 3 the county is in need of a new jail to accommodate inmates with mental health issues. Two days later the sheriff's office said an elevator motor malfunctioned causing smoke in the building but no damage or injuries.
