Two men and two women were hoisted to safety by a helicopter off a cliff in Hacienda Heights, authorities said.
They had become stuck on the cliff at Skyline Drive and Turnbull Canyon Road before the rescue operation started at 8:30 p.m., said Dispatch Supervisor Michael Pittman of the Los Angeles County Fire Department.
The rescue was completed at 9:40 p.m., Pittman said. The four patients were taken to a hospital for evaluation although it did not appear they were injured.
It appeared the four were hikers, he said. There was no vehicle involved.
