Tanzania’s main opposition Chadema party says it will sue some members of the police because of way they manhandled the party’s leadership on Monday. Police arrested, beat and jailed Chadema national chairman Freeman Mbowe, Deputy Chairman Tundu Lissu, and many others on their way to the World Youth Day celebrations organized by the party’s Youth Council. The police said they banned the gathering because it had the potential to incite violence. John Mrema, Chadema’s director of protocol, communications, and foreign affairs, tells VOA’s James Butty ,the action by some senior police officials violated the legal and constitutional rights of the Chadema member.
