Bolivian general who captured Che Guevara investigated over plot against Evo Morales

The retired general who captured legendary revolutionary Ernesto "Che" Guevara was summoned on Friday by Bolivian authorities investigating an alleged plot against President Evo Morales.

Former Gen Gary Prado allegedly exchanged "ultrasecret" encrypted email with Eduardo Rozsa, a Bolivian-born Hungarian who was slain in an April 2009 raid by an elite police unit.

Authorities allege that Rozsa and two other men killed – an Irishman and an ethnic Hungarian from Romania – were involved in a conspiracy to create a separatist right-wing militia in the eastern, opposition-dominated state of Santa Cruz.
