LIUYANG, Hunan: Villagers took to the streets again yesterday in Zhentou township, Hunan province, to protest detentions during the previous day's demonstrations against pollution problems caused by a chemical plant.

The protests were at the local government building and police station, sources said yesterday.

A township government spokesman said villagers on Wednesday staged the protests because they felt they were not being fairly treated for problems caused by pollution from the Xianhe Chemical plant.
