HARARE (Reuters) - A New York Times reporter has been badly injured while in detention in Zimbabwe and needed medical treatment, his lawyer said on Monday.

New York Times correspondent Barry Bearak and a British reporter were granted bail on Monday after being charged with covering Zimbabwe's election without official accreditation.

"They were given bail of 300 million Zimbabwean dollars and the Briton was ordered to reside at the British Embassy and the American was ordered to stay at Dandaro Clinic because he fell in the cells and sustained serious injuries, so he needs medical attention," lawyer Harrison Nkomo said.

Police arrested the journalists at their hotel on Thursday night. Zimbabwean police were not immediately available for comment.
