Police say several hundred garment workers have been sickened at their factory outside Bangladesh's capital, apparently after drinking water there.

Police official Mohammad Jahid says many of the workers were treated at various hospitals after the incident Sunday at East West Factory in Gazipur district.

Jahid says most of the workers suffered vomiting and other stomach problems.

He says up to 4,000 workers are employed in the factory.

Earlier this month, contaminated drinking water sickened 450 garment workers at another factory in the same area.

A building collapse near Dhaka in April killed 1,129 workers, injured many others and highlighted hazardous working conditions in the more than 4,000 garment factories in Bangladesh.
