Justice Uchena denied bail to the MDC supporters including Glenview councillor Tungamirai Madzokera and Cynthia Manjoro, a human rights campaigner who once worked for Zimbabwe Rights Association (ZimRights).
In denying the eight bail Justice Uchena said most of them were a flight risk.
The Judge however granted bail to 12 MDC supporters including Last Maengahama, an executive member of the MDC.
The MDC supporters were charged with contravening Section 47 of the Criminal Law (Codification and Reform) Act Chapter 9:23 for allegedly murdering Inspector Petros Mutedza.
The MDC supporters allege that the police assaulted and tortured them while in police custody as they sought to induce confessions.
