The Star Wars actress Carrie Fisher has suffered a major cardiac episode on a flight from London to Los Angeles, according to a report by the LA Times.
Fisher's flight arrived at LAX at around midday on Friday, and she was rushed to hospital by Los Angeles Fire Department paramedics.
A source told the Times the actress was “in a lot of distress on the flight”. She was reported to have been in a critical condition.
However her brother, Todd Fisher, later told the Associated Press that she was "out of emergency" and in a stable condition.
The entertainment news outlet TMZ reported she had suffered a heart attack rather than a cardiac arrest, and said she received 15 minutes of CPR before the plane landed.
United issued a statement saying Flight 935 from London was met by medical personnel after a female passenger was reported to be unresponsive.
“Our thoughts are with our customer at this time,” the statement read.
An unnamed law enforcement official told NBC Los Angeles that Fisher had suffered a heart attack, and that her condition was "not good".
A spokeswoman for police at LAX airport said: "Los Angeles police responded at 12.15pm to Terminal 7 regarding a female victim who went into cardiac arrest.
"Upon arrival the LAFD (Los Angeles Fire Department) was already performing CPR on the victim and the victim was transported to a local hospital for further medical treatment."
Fisher, 60, rose to fame as Princess Leia in the original episodes of the Star Wars film franchise, a role she reprised in 2015's The Force Awakens.
The actors Anna Akana and Brad Gage wrote on Twitter that they were sat on the same plane as Fisher when the incident occurred.
Akana wrote: "Don't know how else to process this but Carrie Fisher stopped breathing on the flight home. Hope she's gonna be OK.
"So many thanks to the United flight crew who jumped into action, and the awesome doctor and nurse passengers who helped."
Gage wrote: "I'm in complete shock. Anna Akana and I sat in front of Carrie Fisher on our flight from London and she was just taken off the plane by EMTs.
"I don't know what happened. Not really sure what to do right now but I hope she is ok. I hope she is ok."
Fisher had been on tour promoting a new memoir. No representatives for the performer were immediately available for comment, nor were city fire department officials.
Mark Hamill, who played Luke Skywalker in the original films, wrote on Twitter: "As if 2016 couldn't get any worse ... sending all our love to Carrie Fisher."
