A construction worker has fallen to his death at the site of a 2018 World Cup stadium, Russia’s Investigative Committee said Wednesday.

The 43,000-capacity Spartak Moscow arena was one of 12 stadiums awarded matches in an announcement by FIFA and Russian organizers on Saturday.

“A pre-investigation check is under way into the death of a worker who fell from a height at the Spartak stadium building site in Tushino,” the Investigative Committee said.

The man was a 48-year-old steel worker from Russia’s central Saratov region, the statement said, adding that he died at the scene.

The arena in northwest Moscow is scheduled to be completed by 2016.
