Sigifredo Lopez, a former Colombian politician accused of aiding the FARC in his own kidnapping, asked the prosecution to reexamine the evidence against him.
Lopez is the only survivor of 12 deputies of the Valle del Cauca department who were kidnapped by the guerrilla group in 2002 and assassinated five years later.
Investigators are analyzing a FARC training video which allegedly features Lopez instructing guerrillas on how to carry out abductions.
Lopez denied Thursday’s allegations from the governor of the Nariño department that the politician was supported by the Rastrojos, one of Colombia’s most powerful drug gangs, in his Cali mayoral campaign last year.
The allegations against Lopez first emerged after testimony by demobilized guerrilla “El Cabezon” in 2007, who claimed that the politician actively assisted the FARC’s 30th Front.
Lopez remains in Bogota for further police questioning.
