Basketball legend Kobe Bryant is among five people who died in a helicopter crash in the wealthy Southern California residential neighborhood of Calabasas, ESPN has confirmed.
There were no survivors in the crash around 10 a.m. local time Sunday, fire officials said in a press conference. The Sikorsky S-76 helicopter crashed under unknown circumstances, a spokesperson from the National Transportation Safety Board told ABC News.
Witnesses who were mountain biking in the area saw the helicopter in the distress, Los Angeles County Fire Capt. Tony Imbrenda told reporters. It is not known whether the pilot alerted over radio that the aircraft was in distress, Imbrenda said.
It is unclear who the helicopter belonged to or where it originated from and was going to. Firefighters are working on containing the fire that resulted.
Bryant was 41 years old.
