All passengers and crew on a hijacked Colombian airliner were released and the two hijackers surrendered to the authorities in the capital of Bogota. A Colombian airliner with 20 passengers and five crewmembers aboard was hijacked on Monday during a flight from the southern Colombian city of Florencia to the southwestern city of Neiva. The police said the hijackers were wheelchair-bound Luis Ramirez, 42, and his 23-year-old son Linsen, who was as quoted by local media as saying they carried grenades onto the plane. It was reported that Ramirez said he decided to hijack the plane because he was angry for not receiving state compensation for his injury.
