Billionaire Sunjay Kapur, 53, dies suddenly as tragic final words revealed

Witnesses have revealed the tragic final words of Sunjay Kapur, who died suddenly last week.

The Indian-born billionaire, who was chairman of auto components maker Sona Comstar and close friend of Prince William, died on Thursday (June 12).

Kapur, who also had US citizenship, was a keen polo player and was playing the sport in Windsor, UK, when he fell ill and collapsed.

At the time, his team were going head-to-head with Sujan Indian Tigers in the subsidiary final of the Queen’s Cup.

His cause of death is yet to be determined.

Witnesses told The Telegraph that he had shouted: "I've swallowed something," before his collapse.

Others witnesses said Kapur lost consciousness when he bent over on his horse during a break in play.

Tributes have since been pouring in for the polo player who had an estimated net worth of around $1.2 billion.

Kapur was 'a visionary leader,' Sona Comstar said in a statement, adding that his 'passion, insight and dedication shaped the identity and success of our company'.

"He will be greatly missed not only by his family and friends but the local community around his club as he employed so many people and made so many friends – he was fun, kind and generous," a friend also shared in tribute to the news outlet.

"He didn’t distinguish between his grooms or high net worth friends – when he had a party, everyone was invited and everyone was equal."

The billionaire had attended the Doon School boarding school in northern India, which described Kapus as a 'passionate fitness and sport enthusiast and learner for life.'

After finishing his studies at the boarding school, Kapur went on to graduate from the University of Buckingham and took the reigns of his father Surinder Kapur's business after his death in 2015.

Surinder was considered a pioneer in the Indian auto parts industry since the inception of Sona Comstar in 1995.

Kapur also leaves behind his wife, Priya Sachdev. The couple shared a six-year-old son, and Kapur also had two children from a previous marriage.

His death came on the same day an Air India jet destined for London crashed and killed all but one of the 242 onboard, as well as dozens more on the ground in one of the worst aviation disasters in modern history.

Kapur's final social media post paid to those who had died, writing: "Terrible news of the tragic Air India crash in Ahmedabad. My thoughts and prayers are with all the families affected. May they find strength in this difficult hour."
