Staff have "successfully resolved" an incident which took place at a young offenders' institution in Buckinghamshire earlier.
A Prison Service spokesperson said: "Specially trained staff were deployed to deal with an incident involving four prisoners at HMP Aylesbury.
"The incident was successfully resolved at about 1:15 GMT with no injuries to staff or prisoners."
The unit holds more than 400 young men aged between 17 and 21.
A Thames Valley Police spokesman confirmed earlier that they were not in attendance at the incident.
