Veteran Indian actor Om Puri has died at age 66.

Indian media reports say that his death was due to a heart attack, and that he was found in bed at his residence in Andheri, Mumbai.

While he starred mainly in Bollywood films, he was also part of crossover efforts such as The Hundred Foot Journey (2014) starring Helen Mirren, and British comedies East Is East (1999) and West Is West (2010). He also had a cameo in Richard Attenborough's Gandhi (1982).

The actor was awarded the title of Padma Shri, the fourth highest civilian award of India, in 1990, and given an honorary OBE (Order of the British Empire) for his contribution to the British film industry in 2004.
