The accident could delay the delivery of the stadium in Sao Paulo by FIFA's December deadline to have all 12 venues ready as work was immediately halted at the Itaquerao Stadium, which was practically completed before the collapse.
According to Sport24, TV images showed that a huge metal structure buckled atop the stadium, destroying part of the stands and hitting a LED panel installed outside the venue, while a firefighter said that at least three people died in the accident, which happened during the workers'' lunchtime.
The report said that the stadium, which is owned by Brazilian club Corinthians and was initially expected to be built for the Confederations Cup this year, has a seating capacity of almost 70,000 for the opener on June 12 and is scheduled to host other five matches, including a semi-final.
The club and FIFA have extended their sympathies to the families of the victims, the report added.
