Authorities have released the name of a suspected car thief who fell to his death from a loading crane at the Port of Los Angeles after leading police on a chase across the city.

The coroner's office on Thursday identified the man as 23-year-old James Llamas. Officials did not immediately know where he lived.

Llamas fell about 160 feet (49 metres) and died Wednesday night, three hours after he first scaled the crane and stripped naked. It's not clear whether he slipped or jumped.

Police spotted the car reported stolen from a dealership, and an hours-long chase ended at the vast port complex.

Port officials said Thursday that an investigation into the incident will include a probe of how the man breached security and get into the container terminal.
