High powered guns, ammunition and explosives were seized by members of the Inter Agency Task Force (IATF) and Guard and Emergency Branch (GEB) in Santa Cruz on Wednesday afternoon.
The seizure took place after months of surveillance and intelligence gathering.
The cache of weapons, which included 35 guns, 100 magazines and hundreds of rounds of ammunition, was put on full display during an emergency media briefing at the Police Administration Building in Port-of-Spain.
Officers were still counting the rounds of ammunition, which included 5.56 and 7.62 calibre ammunition.
Police Commissioner Erla Harewood-Christopher commended the officers for their efforts in tracking and finding the weapons.
Describing the discovery of the weapons as “historic”, she said the recent seizure was testament to the ability of the police to fight crime.
Referring to the calibre of ammunition seized, she said the danger posed by criminals was real and hoped the exercise had renewed a sense of hope and confidence in the police.
“I want to highlight to the national community the type of weapons and the type of ammunition that was found.
“We have AR15s, we have M16s, mini Uzis, 50-calibre rifles and 12-gauge shotguns.”
Harewood-Christopher also issued a stern warning to criminals that lawlessness would not be tolerated.
“I want to take this opportunity to advise the criminal elements in this country that the police will not be daunted and will not be intimidated by threats. The attack on our public officials will not be tolerated and we will always fight back.”
