A senior official of Tanzania's main opposition party has been arrested amid a crackdown on dissenting voices ahead of next week's general election.
John Heche, deputy chairperson of Chadema, was detained while attempting to attend the treason trial of party leader Tundu Lissu.
In a statement, Chadema alleged that the government planned to "arrest senior party leaders and detain them until after the elections", which will take place on 29 October.
The government has not responded to this accusation.
Chadema said Heche was apprehended as he arrived at the High Court in Dar es Salaam on Wednesday.
