Cameroon’s opposition leader, Maurice Kamto, was placed under house arrest for planning Tuesday’s anti-government protests.
A video showing police vehicles outside the leader’s house has been shared online.
The leader of the Cameroon Renaissance Movement (CRM) told Voice of America that he was neither beaten or detained, but feared that he would be arrested if he stepped out of his guarded house.
Mr Kamto called for protests to demand an end to the Anglophone crisis and a reform of the electoral code.
Demonstrators were dispersed by police in major towns and the opposition says one person was killed and several injured.
He said the protests rose a powerful force and that they will continue until President Paul Biya resigns.
