Worker dies in World Cup stadium accident
He is the third construction worker to perish while working on the Arena Corinthians on the outskirts of Sao Paulo and the seventh to die in building Brazil's World Cup arenas.
Fabio Hamilton da Cruz fell about 25 feet to his death, said a spokesperson for the Santa Marcelina hospital where he was taken.
He was installing floors on the temporary stands being constructed at the ground that will host the Brazil-Croatia opener on June 12, Corinthians said in a statement.
Brazil's Sports Minister confirmed the death and said he would wait for a full report about the incident.
"The Sports Ministry registers its deepest sympathies over the death of Fabio Hamilton da Cruz," it said in a statement. "We express our total solidarity with his family and friends."
FIFA secretary general Jerome Valcke tweeted that he was "very saddened by the tragic death" of the worker and sent his condolences to the man's family and friends.
Fatal accidents have also occurred in Manaus and Brasilia.
Another worker died while working on Palmeiras's arena in Sao Paulo, but that stadium will not be used for the World Cup.
Two workers lost their lives building stadiums for the World Cup tournament hosted in South Africa four years ago.
The Arena Corinthians is among the most expensive of Brazil's 12 World Cup venues and was one of the last to get started.
It is designed to seat 48,000 people but another 20,000 seats are being added for use during the finals.
The construction worker who died was helping to install the temporary stands when he fell, a statement published on the Corinthians website said.
The stadium was supposed to be finished in December but the delivery date was pushed back after two workers were killed in November when a crane toppled over.
Work has been slow since then and there is concern that security may be taking a back seat to haste as workers rush to finish the venue in time.
