Gustavo Vargas Villegas, a former official with Bolivia's aviation authority was arrested and will be held until trial on charges that he misused his influence in authorizing the license of the Bolivian plane that crashed in Colombia while taking the team to Medellin for the Copa Sudamericana.
His father, Gustavo Vargas Gamboa, former chief executive of the LaMia charter airline company, was jailed Thursday pending trial on charges including manslaughter over the Nov. 28 crash.
Both have said they are innocent.
"I am innocent. I did not authorize the operating licenses," Vargas Villegas told reporters on Friday. Vargas Gamboa said on Thursday: "The prosecutors are a bunch of liars
The accident killed 71 people after the plane apparently ran out of fuel, shocking the global soccer community and sparking questions about why the aircraft would have tried to make the international flight with what looks to have been less than the required amount of fuel in its tanks.
