SALEM, Ore. (AP) -- Fighting that a warning shot couldn't halt eventually spread to 59 inmates and has led to what prison authorities call a "modified lockdown" at an Eastern Oregon prison.
The state Department of Corrections say that at one point Thursday afternoon corrections officers fired a shot that restored order at the Snake River Correctional Institution at Ontario.
But fighting resumed and continued for about an hour. One inmate and a staff member got outside medical treatment.
What the department called a "modified lockdown" meant that inmates don't have access to phones but would be allowed to visit.
State troopers are investigating to determine what caused the fighting.
