Miami, November 3 (RHC)-- Warren Anderson, who was CEO of Union Carbide during one of the worst industrial disasters in history, has died of old age.

On December 3, 1984, about 40 metric tons of toxic gases leaked from a Union Carbide plant in Bhopal, India. While the official death toll is nearly 4,000, campaigners say it is closer to 25,000, with many still suffering.

Anderson never faced trial for the disaster although India tried multiple times to extradite him. Activists have rallied for years, calling for Anderson to face charges in India.

Anderson died at a nursing home in Vero Beach, Florida, at the age of 92. The newspaper in Florida read: "Warren Anderson dies here in obscurity."
