A woman thought to be possessed with an evil spirit has been caught on camera giving some bus passengers the horror of their lives.
A shocking video has shown the disturbing moment a 'possessed ' woman terrified bus passengers as she thrashed around, rolled her head and shouted in a satanic voice.
The woman, who has not been identified, was captured on mobile phone video travelling on the public bus in the city of San Luis, central Argentina.
In the footage, she can be seen rolling her head around in circles and yelling unintelligible things in a strangled, deep voice, as she sits in her seat.
At one point, a male passenger approaches the woman to see if she is okay, but she does not seem to see him and continues to moan and thrash around.
Witnesses at the scene later reported that the commuter - who was also seen vomiting on the bus - looked as if she was possessed by an evil spirit.
They said the bus driver was forced to stop the vehicle after frightened passengers pleaded to get off.
The woman remained alone until police officers arrived and took her to the station. It is not known what will happen to her now.
The footage of the incident, taken by a passenger on the bus, was posted online, where social media users remarked on the woman's eerie actions.
Some compared her behaviour to Linda Blair’s character Regan when she was possessed in the cult 1973 film The Exorcist.
One user wrote: "Madness is like gravity...all it takes is a little push."
Another said: "Can you imagine if the lights turn off and when they go on again she is on the roof and her head is spinning around. You can laugh, but if that happened, you’d all s*** yourselves."
The woman's current state remains unclear.
