Hundreds of workers at a garment factory in Bangladesh have fallen ill after drinking suspected contaminated water.
Police estimate the number of sick workers at the sweater factory to be at least 400.
Witnesses say many of the workers were hospitalized after they started vomiting.
The cause of the illness is under investigation.
In April, a building housing several garment factories in Bangladesh collapsed, killing more than 1,100 people and highlighting the garment industry's appalling safety conditions in that country.
Bangladesh is the world's second largest apparel maker. The country's $20 billion industry accounts for up to 80 percent of its annual exports.
Following the collapse in April, Bangladesh closed hundreds of garment factories. The closings were prompted by worker protests over low pay and poor working conditions.
In response to workers' demands, the Bangladeshi government approved labor law changes making it easier for workers to form unions. The government also set up a panel to consider garment worker salary raises.
The factories were later re-opened.
