The demonstration was a continuation of a series of rallies last week, which were sparked by graphic videos showing guards in the ex-Soviet nation brutally beating prisoners and raping them with truncheons and broom handles.
The videos ratcheted up the pressure on pro-Western President Mikhail Saakashvili, whose party is facing a tough opposition challenge in the Oct. 1 parliamentary vote. Saakashvili has accused his main rival, billionaire philanthropist Bidzina Ivanishvili, of timing the release of the videos to the election — the allegations Ivanishvili has denied.
On Monday, Georgia’s Interior Ministry announced the arrest of four opposition-linked suspects. It said the suspects were linked to a candidate of Ivanishvili’s Georgian Dream coalition and alleged that the opposition had sought to encourage police officers to resign in protest over the prison abuse scandal in order to step up pressure on the government.
