Colombian police have arrested a man suspected of planning the 2003 bombing of a Bogota social club, which killed 36 people.
The head of Colombia's Security Administration, Jorge Noguera, said Fernando Arellan was in charge of logistics and financing for the attack.
Officials say two of Mr. Arellan's relatives drove a car packed with explosives into the parking lot of the club. The two men died in the explosion, which injured 160 others.
Speaking to reporters at a Bogota police station, Mr. Arellan denied the charges.
Officials have blamed the attack on leftist rebels, who have been battling government troops and paramilitaries for decades.
