An investigation has been launched after a video of inmates having a party went viral.
The inmates are reported to be from Mdantshane Correctional Service, in the Eastern Cape.
In the video, music can be heard playing in the background while the inmates sip on what looks like wine. Smartphones can also be seen while one of the offenders dance to music.
Meanwhile, Correctional services spokesperson Singabakho Nxumalo said the inmates were identified, a search was conducted and cellphones were confiscated.
Nxumalo added that the offenders were reclassified and would lose some of their benefits.
