An opposition party official says police have released the Zimbabwean opposition leader Morgan Tsvangirai.
Spokesman George Sibotshiwe said Mr Tsvangirai and a group of about 14 officials from the Movement for Democratic Change were released after being held for eight hours at a police station in Lupane, north of the city of Bulawayo.
No charges have been filed.
Mr Sibotshiwe said Mr Tsvangirai had been campaigning in the area when police stopped his convoy earlier today.
Mr Tsvangirai faces off against President Robert Mugabe in a presidential run-off later this month.
