Prosecutors in Harare were forced to end a case against a man accused of subversion after he allegedly posted a comment on the social media website Facebook. According to reports, the prosecution could not find the alleged comment posted by Mahvudzi on Prime Minister Morgan Tsvangari's Facebook page praising Egypt's January revolution. After not being able to recover the comment, there was no case against the man, who spent over one month in jail before being released on bail on March 31. It comes as the country has seen a rise in political tension between the Prime Minister and President Robert Mugabe ahead of elections next year. The long-time rivals agreed to share power after the economy collapsed following the disputed 2008 poll. At least 6 other Zimbabweans are on trial for inciting violence after attending a lecture about Egypt's revolution which toppled veteran leader Hosni Mubarak. The seminar by a university lecturer asked “what lessons can be learnt” – which the prosecution says means they were planning a similar uprising against President Mugabe, who has been in power since 1980, the BBC reported. Police arrested him following a tip-off after he allegedly posted the following message to Tsvangirai's Facebook wall on February 13: “”I'm overwhelmed don't know what to say Mr PM. What happened in Egypt is sending shock waves to all dictators around the world. No weapon but unity of purpose. Worth emulating hey.” BM
