LA PAZ/SANTA CRUZ, Bolivia (Reuters) -Bolivian prosecutors are requesting six months of pre-trial detention for right-wing opposition Governor Luis Fernando Camacho in connection to 2019 social unrest that saw former leftist President Evo Morales flee the country.

Camacho was arrested on Wednesday and taken to the political capital La Paz, sparking protests amid escalating tensions between his wealthy agricultural base in the region of Santa Cruz and the national government. Camacho is facing a possible transfer to a high security jail in El Alto.

Prosecutors have charged Camacho with "terrorism" and are also investigating allegations including attacks on the president and high-ranking state dignitaries, state prosecutor Omar Mejillones said on Thursday.

Prior to a preliminary hearing Thursday, the governor said he was innocent of the charges and his lawyer said he had been "unjustly" detained.

His arrest sparked protests in Santa Cruz, with many people waving the regional flag, and civil groups there called for highway blockades and a general strike on Friday, demanding his immediate release.

"There are times for peace and times for war," said Keyla Garcia, a congresswomen from Camacho's party who led a rally Thursday, quoting the Bible.
