Veteran actor Arun Bali, best known for his work on TV show `Swabhimaan` and blockbuster hit `3 Idiots`, died on Friday morning at his residence in suburban Mumbai. He was 79.

Bali`s son Ankush said his father was suffering with Myasthenia gravis, an autoimmune disease caused by communication failure between nerves and muscles, for which he was admitted to a hospital early this year.
