Union Carbide still haunts victims of 1984 disaster as parent company becomes sponsor of 2012 games.

The naming of Dow Chemical as an official sponsor of the 2012 Olympic Games in London has caused outrage in India.

Dow Chemical is the parent company of the firm responsible for the world’s worst industrial disaster, the Union Carbide gas leak in Bhopal, India.

Twenty-seven years after the initial leak, residents in Bhopal still suffer from the long-term medical complications of the Union Carbide disaster and are seeking justice, proper compensation and medical care.

In a statement to Al Jazeera, the London Organising Committee for the Olympic Games (LOCOG), said: “Having carefully looked in to this issue and based on everything we know and have seen from Dow, we stand behind them both as a worldwide sponsor of the Olympic movement and as a supplier to LOCOG.”

Al Jazeera’s Sohail Rahman reports from Bhopal, where the community still gathers every year to mourn the dead and demand justice.
