MANAUS, Brazil - Brazil was rocked Saturday by a fourth fatal World Cup stadium accident as a young construction worker fell to his death, heightening safety worries barely six months from kick-off.
The latest fatality, at the Manaus Arena in the northern Amazonia region, will add scrutiny to the host nation's preparations, with some stadiums behind schedule and extra shifts being worked in a push to be ready for the football extravaganza.
Marcleudo de Melo Ferreira plunged 35 metres (115 feet) in the early hours while working on the roof of the US$200 million (S$251 million), 42,000-seat capacity arena. He was taken to hospital but died before dawn.
Brazilian media reported that the 22-year-old fell after a cable broke as he prepared to finish a night shift. The venue is currently 93 percent complete and has around 1,900 people working around the clock to finish its construction.
The accident brought to five the number of deaths at event sites, and comes two weeks after two people died at the Sao Paulo stadium scheduled to host the June 12 opening match between Brazil and Croatia.
In an unrelated incident, a construction worker died of a heart attack while working on a new convention centre near to the stadium amid allegations from his family that he was overworked.
Saturday's stadium death was the second fatality at the Manaus Arena, which will host England's opening match on June 15 against Italy, plus three other World Cup matches.
After the first death in the tropical city's stadium, the state public prosecutor demanded dozens of upgraded security measures, but there has been no word on any progress.
A January report found working conditions were unsatisfactory amid claims workers had not been issued with sufficient safety equipment.
FIFA, which has played down concerns over stadium delays, expressed its sadness at the latest construction death.
"We would like to send our most sincere condolences to his family, relatives, colleagues and friends," football's governing body said in a statement.
In addition to the two Manaus accidents and the double fatality in Sao Paulo - a venue that organizers say will only be completed in mid-April - a further death occurred at a new stadium in Brasilia last year.
