Police in Colombia have presented to the media 23 alleged drug traffickers captured in a US-Colombian operation earlier this week. Colombian and US officials on Friday said they arrested some 30 people and seized 21 airplanes in an operation against a major cocaine trafficker. They also announced a 2.7 million US dollars of reward for the notorious trafficker, Daniel \"Loco\" Barr-era. Those arrested were mostly pilots and air traffic controllers and most of the planes were seized in Guatemala and Honduras. The operation was to dismantle a drug network that was moving 10 tonnes of cocaine each month to the US through central America.
