Zimbabwe police arrested the main opposition's youth leader on Thursday, after accusing opposition supporters of running amok in central Harare earlier this week, state radio reported. It said Movement for Democratic Change (MDC) youth leader Nelson Chamisa, accompanied by his lawyer, handed himself in to police. Police and MDC officials were not immediately reachable for comment. On Monday, police said a small group of opposition protesters ran through central Harare, smashing a couple of shop windows and distributing fliers condemning the results of last week's parliamentary elections, which they said were rigged in favour of the ruling ZANU-PF party. But the MDC has denied involvement in the protests and said they could be the work of ZANU-PF. --SP 2013 Local Time 1713 GMT
