With one of their members murdered and another in hospital after being shot members of the Prisons Service say they have received information of another threat.
The information, they say, have been received from the National Operations Centre which relayed a threat stating that five more prison officers will be killed. The threat is being investigated.
It comes one day after prisons officer Otis Johnson was shot moments after he left the Frederick Street Prison on Sunday night.
According to police, Johnson was walking near Royal Castle around 7.30 pm when a car pulled up. Occupants of the car shot him in the back and abdomen. A passing ambulance took him to hospital.
Prisons officers at the prison on Sunday told the T&T Guardian that some members were willing to resign. A friend of Johnson's said after Andell Primus was killed on Friday he and Johnson were contemplating quitting.
Primus, 27, was shot three times in the head by gunmen, thrown out of his vehicle and left for dead at Red Hill, Morvant.
Primus, a father of a two-month-old baby girl, died while being taken to the Port-of-Spain General Hospital.
Prisons officers on Sunday night were escorted to their vehicles by their heavily-armed colleagues as a police jeep with two officers kept a close eye on the prison.
Prisons officers were heard telling videographers that their lives were in danger and they videotaping them was making it worse.
In a media release yesterday Commissioner of Prisons Sterling Stewart condemned the attack on his officers and said enough was enough.
"The attack on the lives of our nation's prisons officers continues and I want first of all to urge our officers to stand strong, stand firm and unwavering in their duties but I also urge them to be vigilant and careful as they go about their duties and their daily walk of life.
"We will allow the police to do their job to bring these killers to justice. For too long the lives of my officers have been threatened and snuffed out by the undesirables in society and I want to state categorically that enough is definitely enough," Stewart said.
In a brief telephone interview general secretary of the Prisons Association Gerard Gordon said the association had given the authorities one week to implement policies to save its members. He encouraged his members not to make hasty decisions and resign.
