Four persons, including a woman, 38, have been charged with the $5.5 million robbery at Piarco International Airport on December 6.
But police have recovered only $250,000 of the stolen loot.
The woman accused, Kizzy Bernard, was charged with money laundering and receiving stolen money.
Kenol Singh, 35, also of Longdenville, faces a money laundering charge and is jointly charged along with Kevon Findley, 42, and Abdul Mohammed, 38, with robbery with aggravation.
Findley and Mohammed, both of Diego Martin, are separately charged with possession of marijuana for the purpose of trafficking.
Singh unsuccessfully made a habeas corpus application before a High Court Judge last Friday.
The four will appear before an Arima Magistrate on Monday.
The investigation into the multi-million dollar robbery was led by DCP Crime Harold Phillip.
Charges were laid Saturday nightfollowing advice received from acting Director of Public Prosecutions (DPP), Joan Honore-Paul.
On December 6, around 11 am, four masked men, dressed in camouflage wear and carrying automatic weapons, held up an Amalgamated Security truck and took the money which was being transferred to a Caribbean Airlines flight to Tobago.
The men escaped in a pick-up truck which was found abandoned one hour later at Oropoune Gardens, Piarco.
