VISAKHAPATNAM, India (Reuters) - A clogged cooling system was the likely cause of a temperature surge in a storage tank which led to a gas leak at a chemical plant in India, killing 12 people, three state government investigators told Reuters.

They said workers at LG Polymers, a unit of South Korea's LG Chem near the southern city of Visakhapatnam, did not use a warning system to alert local residents but informed company management after the leak in the early hours of May 7.
