Four members of Women of Zimbabwe Arise held by Harare police since a demonstration last week were released on Tuesday without being charged.
The activists included Jenni Williams, WOZA national coordinator, and Magodonga Mahlangu, another leader of the group, which demonstrated at the Harare offices of the Zimbabwe Electricity Supply Authority or ZESA on Thursday against high electric power rates.
Their release was ordered by the office of the Attorney General after five nights detention, WOZA sources said, citing insufficient evidence. Members Clara Manjengwa and Celina Madukani were also released Tuesday.
WOZA Coordinator Williams told VOA Studio 7 reporter Sithandekile Mhlanga that the group will sue the government for unlawful arrest and detention.
