A 27-year-old construction worker died Friday after falling into a well, according to the Los Angeles Fire Department.
The man was being lowered into the 50-foot-deep well by a rope or cable when he became untethered and fell, landing face-down in water and debris, said Brian Humphrey, a fire department spokesman.
His co-workers immediately called 911 and members of the department's urban search-and-rescue team were dispatched to the site in the 900 block of North Bel Air Road, where a large home is under construction.
A rescuer lowered into the well found the man "beyond medical help," and he was declared dead at the scene, Humphrey said.
The worker's identity was not released, pending positive identification by the Los Angeles County coroner's office, which also will determine the cause of death.
Cal/OSHA, which investigates workplace accidents, was notified and was sending investigators, Humphrey said.
