Iconic singer-composer Bappi Lahiri, who introduced synthesised disco beats to Bollywood, died at a hospital in the western city of Mumbai around midnight on Tuesday. He was 69. Lahiri, who had Covid last year, was rushed to Mumbai's CritiCare Hospital at 11.30pm on Tuesday by his family members after he complained of discomfort. He was declared dead by the hospital doctors a little later. Hospital director Deepak Namjoshi told the media on Wednesday morning that Lahiri had, in fact, been admitted to the hospital for a month for various health issues and was discharged only on Monday.  "But his health deteriorated on Tuesday again. When the family got him to the hospital, his blood pressure was low and the pulse couldn’t be felt. We tried to revive him but it was too late," Dr Namjoshi said. "Lahiri died due to obstructive sleep apnea shortly before Tuesday midnight," he added. Originally from Bengal, Lahiri shot to fame in Bollywood in the 1980s and 1990s for his music in blockbusters like 'Wardat', 'Disco Dancer', 'Namak Halaal' and 'Sharaabi'. His last Bollywood song was for 'Baaghi 3' in 2020.
