Two workers who were cleaning a tank at a leather tannery at Pallavaram, India, died after the side wall collapsed on top of them, last week.

Police have named the workers as Akram Ansari (17) and Abith Hussain (24). A third worker, Ajay (25), is still in hospital following the incident.

“On Thursday night, they were cleaning a tank which would be filled with chemicals used to wash the leather," a police officer said. "At around 9.30pm, the side wall of the tank collapsed and fell on them. While Akram died on the spot, Hussain and Ajay were taken to Chromepet government hospital."

Hussain died in hospital of cardiac arrest, since he had consumed some of the chemicals that fell over him, said the police. An investigation into the incident is under way.
