Police in India have arrested 12 people in relation to a styrene gas leak at a chemical plant in May, which killed 12 people and left hundreds ill.
Those detained are all employees of South Korea's LG Polymers, the company that runs the plant, including the CEO and two directors.
An investigation found the company was negligent and that warning systems at the plant in Visakhapatnam weren't working.
LG Polymers has yet to respond to the arrests.
