Police seized more than 4.5 tons of marijuana which allegedly belonged to the Rastrojos drug gang, and was apparently being transported towards the Venezuelan border.
The drug haul was worth some 8 billion pesos ($4.5 million), according to the National Police, and was being transported in a vehicle in the Norte de Santander department. The marijuana was divided into more than 80 packets, and hidden beneath a load of onions.
Police arrested four men in the operation, two in the vehicle that was carrying the drugs, and two more in a vehicle that was traveling behind.
The marijuana had been transported from Cauca, on Colombia's Pacific coast, according to reports.
