Officials say police have raided the headquarters of the political party of Zimbabwe's prime minister and arrested three staff members.
It appeared to be the latest installment of a crisis in the country's unity government, which united Prime Minister Morgan Tsvangirai with Zimbabwe's longtime ruler Robert Mugabe in an unlikely power-sharing agreement in 2009.
Last week, Tsvangirai said he wants out of the government after police arrested one of his top political allies.
On Monday, his Movement for Democratic Change said 30 police officers "besieged" its headquarters and arrested a youth leader and two security guards on duty there late Sunday.
Attorneys are still seeking information of any allegations against them.
