A woman has reportedly vanished from sight just moments after she live-streamed a Facebook video from inside a stranger's car.

Jessica Lynn Andress, a 26-year-old woman has vanished from sight just moments after reportedly live streaming a chilling video from a mystery man's car and then making a disturbing 911 call claiming she had been robbed.

According to The Sun UK, the young woman posted the Facebook Live video last Friday from the passenger seat of a vehicle before making a worrying call to police.

“We were robbed; my clothes, my money, my phone,” she said before hanging up, according to the Detroit Free Press.

Jessica had left on Thursday morning on a bus to Detroit to meet a man she met online.

Her father James reported her missing when she did not return the following day.

The Facebook Live video, which was re-posted by her uncle and later removed, she briefly pans to a man in a red shirt who was behind the wheel.

The 90-second clip shot at night sees her travelling on a motorway in an unknown location.

It is unclear whether the driver was the man she was reportedly travelling to meet.

Not long after posting the video, Andress called 911 from a phone at the Wake Forest Baptist Trauma Centre in North Carolina, which is more than 600 miles from Detroit.

Authorities said she has not been heard from since the call.

Her uncle Larry McQuiston made a plea on Facebook for help tracking her down.

“We need to identify who the man in the video is and possibly where she is,” McQuistone wrote.

“She is believed to be in danger.”
