POLICE took away Zimbabwe`s main opposition leader Morgan Tsvangirai in the middle of the night for questioning about a demonstration planned for today, his lawyer says.
"The police are saying they want to know what he is planning to do today," lawyer Alec Muchadehama said.
Mr Tsvangirai`s Movement for Democratic Change (MDC) planned the march to press veteran President Robert Mugabe for a new constitution to guarantee parliamentary and presidential elections due in March are free and fair.
The MDC launched a legal challenge yesterday to a police ban on the march.
MDC secretary-general Tendai Biti said Mr Tsvangirai was picked up from his home in a suburb of the capital Harare by plainclothes officers.
"He was picked up at around 4am (11pm AEDT) in respect of the intended demonstration. His mobile phone is now off and we are really worried," he said.
The lawyer said police also detained another MDC leader, Dennis Murira.
Mr Mugabe has been in power since independence from Britain in 1980.
Mr Tsvangirai was last arrested in March 2007 along with dozens of opposition officials ahead of another planned march.
He says police beat him up in custody. They deny this.
The police had initially granted permission for today`s march, which the MDC called to protest against a crumbling economy blamed on government mismanagement as well as to press for a new constitution.
Yesterday, Mr Muchadehama said the Harare magistrates court would hear an application today on overturning the ban, which police say was prompted by fears the demonstration would degenerate into violence and looting.
Zimbabweans have tended to shy away from demonstrations in recent years, mainly from fear of a heavy-handed response by security forces.
