Terrified passengers watched in horror as a bendy bus split in two during what was supposed to be a normal journey.
A commuter filmed inside the bus after hearing a strange screeching noise from what they presumed was the brakes.
One woman on board, standing close to the middle join of the bus, can be seen looking down at the moving section.
The all of a sudden the front tears away from the back of the bus leaving people getting out of their seats and heading for the doors.
The dramatic footage was filmed in the city of Palhoca in Brazil and later uploaded to Twitter.
