The children suffering from diseases in the wake of gas tragedy took part in various games organised on the occasion in protest.
Addressing the opening ceremony of the "Special Olympics" at Arif Nagar Stadium near the defunct Union Carbide plant, former Olympian and hockey player, Jalaluddin Rizvi said, "as an Olympian, I am ashamed that the organisers of London Olympic have made Dow Chemicals a sponsor till 2020.
"I and 25 of my fellow Olympians wrote to the organisers of the Olympic Games and requested them not to make Dow Chemicals a sponsor and provide it with an opportunity to 'greenwash' its crimes. But the organisers which include the British Olympians such as Sebastian Coe did not respond."
Dow is the current owner of Union Carbide from whose plant in Bhopal the deadly methyl isocyanate gas leaked on the intervening night of December 2-3, 1984, killing thousands of people and maimed lakh of others.
