Steel worker Jaleshwar Prasad, 48, died at Al Khor Hospital on Wednesday (April 27) after falling ill on the stadium site, 50 kilometres north of Doha.

Qatar’s Supreme Committee for the Delivery and Legacy (SCDL) of the 2022 World Cup have denied it was caused by working conditions which the country is under pressure to improve.

"Al Khor Hospital reported the cause of death as cardiac arrest," said the SCDL in a statement.

"The family of Mr Prasad were informed of the tragedy immediately.

"A full investigation is underway."

According to the SCDL’s February Workers’ Welfare Progress Report, Prasad is the third Indian expat employed on a World Cup site to die of a heart attack in the last six months. 

The report states that a 52-year-old painter working on the Khalifa International Stadium in Doha went into cardiac arrest during lunch at one of the site’s dining halls and died in hospital in October.

It is also said that a 55-year-old truck driver suffered a heart attack in his accommodation in January and later passed away. 

Approximately 5,100 construction workers from Nepal, India and Bangladesh are building stadiums in the wealthy Gulf nation. 

No work-related fatalities have been recorded by the SCDL on World Cup sites, but in a review for the Qatari Government in 2013, international law firm DLA Piper found evidence of dozens of work-related deaths across Qatar among migrant labourers from South Asia.

Claims that there are higher instances of heart attacks among construction workers have been denied by Qatar's Government, which doesn’t publish independently-verified statistics on worker-related injuries and fatalities.

Last month, FIFA President Gianni Infantino announced a panel will be created by FIFA to oversee working conditions at World Cup sites in a bid to allay growing human rights concerns.

In what was his first working trip to the country, which was controversially awarded the rights to FIFA’s flagship quadrennial competition in December 2010, Infantino revealed the group would include "relevant sectors of civil society and other relevant FIFA stakeholders".

The establishment of the panel comes amid continued criticism from Amnesty International, which recently published a damning report into alleged labour abuses at the Khalifa International Stadium and other venues over the treatment of migrant workers building infrastructure for the tournament. 

"Workers dying suddenly from heart attacks is something we hear about often, the causes are not always clear," Amnesty International's Gulf migrants rights researcher Mustafa Qadri said.

"But we're moving now into the hottest time of the year when the risk of fatality increases.

"When a worker dies, Qatar needs to get to the bottom of what happened.

"People's lives are in danger."

The build-up to the event in six years’ time has been littered with suggestions by Amnesty International that FIFA and the SCDL have persistently done little to address "rampant migrant labour abuse".

It came after the publication of high death toll figures among migrant workers, with it claimed as many as 1,200 may have died since 2010.

Following the release of the Amnesty International study, entitled The ugly side of the beautiful game: Labour exploitation on a Qatar 2022 World Cup venue, an independent report written by John Ruggie - a professor at Harvard Kennedy School in Massachusetts and one of the world's foremost human rights experts - was released.

It made 25 recommendations to FIFA, including that tournaments already awarded should be moved to different host countries if human rights abuses continued.
