[JURIST] Morgan Tsvangiari, the leader of the Zimbabwe opposition party Movement for Democratic Change (MDC), was arrested and detained Saturday at Harare International Airport. Officials say he was released after a 20 minute detention. Tsvangiari, recently acquitted of treason, had just completed a tour of Europe and Africa. The government, controlled by Psreident Robert Mugabe's Zimbabwe African National Union-Patriotic Front (ZANU-PF) had criticized him heavily in his absence. Papers seeking appeal of Tsvangiari's acquittal were filed by government officals earlier this week. AFP has more.
