Freed Tsvangirai on campaign trail
Zimbabwe's opposition presidential candidate has resumed campaigning after spending nine hours in police detention in the country's second main city.
Morgan Tsvangirai's party said he had left Bulawayo to continue his campaign.
It says he is "undeterred" by the detention and accuses President Robert Mugabe's government of trying to steal the June 27 presidential run-off.
According to his party, police released Tsvangirai late on Wednesday after charging him with "attracting a large number of people".
Police have broad powers to restrict gatherings in Zimbabwe.
Party officials say Tsvangirai had been campaigning in the area when police stopped his convoy on Wednesday.
