The state Department of Corrections grappled with disturbances at four North Florida prisons during the past week but said "normal operations" had resumed Monday.
The department announced last week that a "major disturbance" involving several hundred inmates had occurred Wednesday at Holmes Correctional Institution.
It said Monday that another major disturbance had occurred Friday in dorms at Gulf Annex Correctional Institution.
Also it, said two dorms at Mayo Correctional Institution were involved Friday and Saturday in work stoppages and attempts to incite disturbances and that one dorm was involved in a disturbance Saturday at Jackson Correctional Institution.
The Jackson disturbance came after what the department described as a "serious inmate on inmate assault."
In announcing the return of normal operations, Corrections Secretary Julie Jones issued a prepared statement Monday that said staff members had "worked tirelessly throughout the last several days and nights to protect our state in many challenging situations."
In each incident, teams from nearby prisons responded to help bolster staffing.
The department said it will conduct investigations of each incident.
