Four inmates have been injured at the remand section of the Maximum Security Prison in Arouca.
The injuries occurred after officers intervened in what officials have described as a tense situation.
In an official statement, the Prisons Service says at about 1 pm on Monday, a tense situation developed at the remand prison which required the intervention of additional officers to quell the situation.
The statement explains that officers had to use force to restore order, this after several hours of attempting to execute their duties in a professional manner and it resulted in four inmates sustaining non-life threatening injuries.
The statement also said that several threats were made against members of staff as they carried out their duties.
The prison service says the acting Commissioner of Prisons, Dane Clarke has launched a probe into the incident.
In addition, the matter has been relayed to the other arms of the protective services in light of the threats made against officers.
Police Commissioner Gary Griffith said he is currently looking into what happened yesterday and will meet with the relevant authorities.
