U.S. Customs and Border Protection said Saturday they seized 42 pounds of cocaine aboard a coastal freighter on the Miami River.
According to CBP, the cocaine has an estimated wholesale value of $400,000. The seizure was made on February 28th.
The drugs were reportedly concealed behind the interior walls of one of the vessel's cabins.
CBP officers made the discovery when they used a power tool to drill into a wall, and found a white powdery substance on the tip of the drill.
CBP also said the coastal freighter, M/V Carib Trader II, had traveled from Gonaives, Haiti, and stopped in Bimini, Bahamas before stopping in the Miami River.
