From AFP:

A human rights group has condemned Chinese police for allegedly stripping and beating a prominent Shanghai lawyer during a nine-hour detention last week.

Police summoned Zheng Enchong, who has advised residents claiming to have been forcibly evicted, on Wednesday as part of an “economic investigation”, the Hong Kong-based China Human Rights Lawyers Concern Group said.

Calls to the Shanghai police went unanswered and Zheng was not immediately available for comment on Tuesday.
