NEW DELHI — Popular Indian comedian Raju Srivastava has died aged 58, his family has confirmed.

Srivastava was being treated at a hospital in the capital, Delhi, following a heart attack on 10 August.

The comedian had been taken to hospital and put on life-support after experiencing chest pain and collapsing while working out at the gym.

Last week, his family said that Srivastava was recovering slowly but remained on ventilator.

Srivastava joined the entertainment industry in the 1980s as an actor in Hindi films.

He shot to fame in 2005 after participating in The Great Indian Laughter Challenge, a reality show for stand-up comedy.

Prime Minister Narendra Modi led the tributes at the news of Srivastava's death.

Srivastava was known as the common man's comedian.

He was born in 1963 in Kanpur city in northern state of Uttar Pradesh to poet Ramesh Srivastava. As a child, Srivastava was known to be fond of mimicking film stars.

His uncanny ability to mimic Bollywood star Amitabh Bachchan was well known in the world of Hindi-language comedy.

Srivastava began doing comedy in the 1980s when the state-run Doordarshan TV was the audience's main source of entertainment.

His first comedy sketch Hasna Mana Hai (Laughter is Banned) appeared in the form of an audio cassette.

In an interview, Srivastava recalled travelling with friends in a tuk-tuk as the driver played his cassette.

"We teased him saying, 'What are you listening to, man? Stop this and put on something good.' But the driver responded, 'Oh no, brother, this Srivastava makes me laughs a lot,'" he said.

In the late 1980s, Srivastava moved to Mumbai to be closer to Bollywood.

His debuted as an actor in the Salman Khan starrer Maine Pyaar Kiya. He went on to appear in several popular films like Baazigar and Toilet: Ek Prem Katha.

But comedy remained his mainstay.

Srivastava captivated audiences as a participant in The Great Indian Laughter Challenge, and was known for the spontaneity in delivery of jokes.

In one interview, he joked that he wore bright, colorful clothes because "my shows are held in fairs in cities like Lucknow and Patna, where there is a huge crowd. So when I wear these clothes, people can spot me from afar."

Like many Indian entertainers, Srivastava also dabbled in politics.

He was fielded from Kanpur by the Samajwadi Party in 2014 national election. He later withdrew from the race. Months later, he joined the ruling Bharatiya Janata Party (BJP).

On Wednesday, Samajwadi Party Akhilesh Yadav condoled his death. "He came from a poor family. With his talent and hard work he made his presence felt in the world. There are very few talented comedians like him." — BBC
