A security breach has forced authorities to shuffle some high-risk inmates yet again – this time back to the army’s Teteron Barracks, Chaguaramas.

Newsday understands some inmates, all classified as high-risk and accused of plotting murders, kidnappings and gang wars from behind bars, were yanked out of Staubles Bay, on August 21, after it was uncovered that contraband – a cellphone and charger – was inside the coast guard’s headquarters.

The prisoners were originally removed from Building 13 at the Maximum Security Prison, Arouca, on July 18, the very day a state of emergency was declared after intelligence exposed a deadly conspiracy to assassinate police, prison officers and even members of the judiciary.
