Bolivian President Evo Morales announced the arrest of a man convicted for the 1980 assassination of socialist leader Marcelo Quiroga Santa Cruz during the course of a military coup led by Luis Garcia Meza.

Morales said at a Sunday night press conference that Felipe Froilan Molina Bustamante, alias "Killer," was arrested at a secret hideout on the roof of a home in the Cota Cota neighborhood in La Paz after a two-hour search by 80 police officers who came to the site after following the fugitive's daughter.

The president said that "Killer must know the location of the remains of Quiroga Santa Cruz," who disappeared July 17, 1980, when paramilitaries attacked the headquarters of the COB labor federation during Garcia Meza's coup.

The murder and disappearance of the leftist leader is considered to be one of the worst political crimes in Bolivia's history.

The Supreme Court in October 2010 sentenced Molina Bustamante and two other paramilitaries to 30 years in prison without parole for crimes committed during Garcia Meza's 13-month dictatorship.

Morales said that the arrested man should provide information about the location of Quiroga Santa Cruz's remains for humanitarian reasons after authorities recently resumed searching for them.

Garcia Meza has been held in a high-security prison in La Paz since 1995. EFE
