SIOUX FALLS, S.D. (AP) — A judge says an inmate at the South Dakota State Penitentiary accused of assaulting another inmate must serve eight years in prison.

Authorities say 39-year-old Esteven Cruz-Febus and two other inmates, Daniel Augustine and Christian Witt, assaulted an inmate in the recreational yard at the penitentiary.

Cruz-Febus and the co-defendants allegedly stomped, punched and kicked the victim in the head and body multiple times.

Augustine and Witt were sentenced earlier.
