Prisons Officer Richard Francis was shot and killed when three men invaded his Oasis Gardens home in Chaguanas on Friday evening.
The Prison Service says the TTPS is currently investigating and more information will be forthcoming.
Acting Prisons Commissioner Dennis Pulchan has condemned the action of the perpetrators which he has described as “cowardly and heinous”.
An emergency meeting was called with members of the Executive and they are working with police to have the persons responsible, arrested and charged in the shortest time possible.
Commissioner Pulchan is also urging officers to continue to be alert and exercise caution both on and off duty.
The victim was a member of the Prison Service for over 24 years and was last assigned to the Remand Prison. He is the 24th officer to be murdered over the past 30 years.
