Chennai: Day after 11 people were killed in anti-sterlite protest in Tamil Nadu, the Madurai bench of the Madras High Court on Wednesday stayed Sterlite Copper's expansion in Thoothukudi (Tuticorin).

The company had filed an application in February this year to obtain environmental clearance to expand its plant in the coastal city.

The expansion would have entailed doubling of the capacity of the smelter to 800,000 tonnes per year.
