HMP Hewell disorder as inmates refuse to return to cells
Google Specially-trained officers were used to deal with a disorder at a prison after inmates on a wing refused to go back into their cells.
It happened on Friday night at HMP Hewell, near Redditch, Worcestershire.
The Prison Service said it was not a riot, and no staff or prisoners were injured.
The incident lasted less than four hours on one wing of the category B jail, which holds more than 1,200 inmates.
A Prison Service spokesperson said: "Staff at HMP Hewell successfully resolved an incident in one wing of the prison on Friday 7 June.
"We do not tolerate indiscipline that threatens other prisoners and staff and those involved will be punished."
In February, a report said the prison was not "providing a service fit for the 21st Century" for inmates or staff.
The "poor environment" at HMP Hewell was highlighted in the Independent Monitoring Board's (IMB) annual report.
