Zimbabwe police have arrested an opposition lawmaker accused of organizing violent youth protests against the outcome of last week's election.

Police seized Nelson Chamisa over Monday's march in Harare, where protesters allegedly smashed shop windows and harassed bystanders.

Officials detained at least two youths following the protest.

The opposition Movement for Democratic Change has denied calling the action by marchers who handed out pamphlets criticizing the results of parliamentary elections.

Opposition leaders have rejected the outcome over alleged voting irregularities and are calling for a new poll.

The ruling Zanu-PF party claimed a major victory in Thursday's vote, winning a two-thirds majority in the legislature.

The United States and Britain say the voting process strongly favored the ruling party.
