MITCHELL, S.D. (AP) - A Davidson County correctional officer is being treated for multiple facial fractures after an assault by an inmate.

KSFY television reports that Officer James Dietz was doing his rounds shortly after 10 p.m. Tuesday when he discovered evidence of "fishing." The practice involves an inmate attaching an object to dental floss to toss it across to another inmate.

When Dietz confronted the inmate, the man attacked the officer, requiring two other officers to assist. One of the assisting officers used a Taser to subdue the man.

Dietz was transported to a local hospital.

The name of the prisoner, who is serving time for burglary and reckless burning, was not released.

Jail Administrator Don Radel says the jail hasn't had an intentional assault on an officer in about a decade.
