Singer-composer Wajid Khan of the music director duo Sajid-Wajid, popular for their work on superstar Salman Khan's films like Wanted, Dabangg and Ek Tha Tiger, died in the wee hours on Monday in a Mumbai hospital.
The cause was coronavirus.
The 42-year-old singer had underlying kidney issues.
"He died of cardiac arrest," Wajid's brother Sajid told PTI while confirming that the musician had tested positive for COVID-19.
Composer Salim Merchant, who first confirmed the news of Wajid's death, said the composer was hospitalised recently where his condition deteriorated.
"He had multiple issues. He had a kidney issue and had a transplant a while ago. But recently he got to know about kidney infection... He was on the ventilator for the last four days, after his situation started getting worse. Kidney infection was the beginning and then he got critical," Salim told PTI.
A source close to the family also confirmed the coronavirus diagnosis.
"He had coronavirus. When you already have heart and kidney issues, your immunity is low. His situation worsened in the last few days," the source added.
The composer duo made their Bollywood debut with Salman's 1998 movie Pyaar Kiya Toh Darna Kya and went on to work on the actor's films including Garv, Tere Naam, Tumko Na Bhool Payenge, Partner and the popular Dabangg franchise.
Wajid also sang for Salman chartbusters Mera He Jalwa, Fevicol Se and for Akshay Kumar in Chinta Ta Chita Chita from Rowdy Rathore, among others.
He recently co-composed Salman's songs Pyaar Karona and Bhai Bhai, which the actor released on his YouTube channel.
Wajid and brother Sajid served as mentors on singing reality shows Sa Re Ga Ma Pa 2012 and Sa Re Ga Ma Pa Singing Superstar.
The composers also scored the IPL 4 theme song, Dhoom Dhoom Dhoom Dhadaka, which was sung by Wajid.
Soon after news of the composer's demise broke, many from the film fraternity took to Twitter to pay tributes.
Priyanka Chopra said she will always remember Wajid's smile.
'The one thing I will always remember is Wajid bhai's laugh. Always smiling. Gone too soon. My condolences to his family and everyone grieving. Rest in peace my friend. You are in my thoughts and prayers,' she posted on Twitter.
Actor Parineeti Chopra said Wajid was one of the 'nicest'/ men in the industry.
'Always singing. All heart. Always positive. You will truly be missed Wajid bhai,' she tweeted.
