The Oregon State Penitentiary was placed on full lockdown again following two additional inmate fights that took place Tuesday evening and Wednesday morning. And, as a precautionary measure, an “Institution Emergency” has formally been declared which allows for an agency-coordinated response. These fights are in addition to two inmate fights that broke out Sunday, April 24, in the institution's Recreation Building and Recreation Yard, involving a total of 81 inmates. Authorities say, based on information that has been made available since Sunday, all four incidents appear to be connected with two inmate groups.
