Colombian police said on Friday they had seized two tons of cocaine hidden in cement bags in a mule-drawn cart on a main road in the northeast province of Cordoba.
The mule-driver was arrested, police colonel Jaime Velasco said, adding that they were "trying to establish the origin of the drug shipment."
The seizure, made on the road linking Monteria, the capital of Cordoba, to Arboletes, a smaller Cordoba settlement, is the largest made by the country's Sijin Judicial Intelligence Service in two months.
In another operation, army troops discovered a cocaine manufacturing complex in the central Colombian department of Meta and they also seized two tons of explosives.
An army statement said the complex appeared to belong to the Revolutionary Armed Forces of Colombia's 44th Troop.
The army's Special Anti-Drug Brigade carried out the so-called Operation Tormenta, or Storm, during which several minefields were dismantled and a number of weapons seized.
