LAS VEGAS - A worker has died of injuries after a fall at a Las Vegas casino-resort construction site, a state safety official said Friday.

"There is one fatality," Stephen Coffield, acting chief administrator of the Nevada Occupational Safety and Health Enforcement office in Las Vegas, said of the mishap at the $2.8 billion Fontainebleau-Las Vegas site.

The identity of the dead man was not immediately made public. Coffield said no information about the case would be released until his agency completed an investigation.

The worker was one of three men who fell Thursday morning from atop a 30-foot wall at the high-rise project site, Clark County fire spokesman Scott Allison said.

Harness safety systems broke the fall of two men, but failed for the third man, Allison said. That worker plunged into a 10-foot hole.

All three men were taken to Sunrise Hospital and Medical Center in Las Vegas, where the conditions of the other two men were not immediately available Friday.

The Fontainebleu is being built by privately held developer Fontainebleau Resorts LLC on 24.5 acres just east of Las Vegas Strip. It is due to open in late 2009 with 3,889-rooms, a casino, hotel, condominium and spa.
