Cartersville - Fire officials say several bystanders held up a kiddie roller coaster that had begun to collapse in Georgia, allowing six children and one adult to escape.

Georgia Insurance and Safety Fire Commissioner spokesperson Glenn Allen says the group held the Oriental Express roller coaster in place on Thursday evening until wood or cement blocks could be put in place to stabilise it.

A video posted on social media shows more than a dozen people holding up the coaster at the Bartow County Fair in Cartersville.

Allen says there were no injuries, and a track malfunction is likely what caused the accident. The ride's been dismantled.

Allen says Florida-based company Carol Stream operated the fair's rides. The company did not immediately respond to a phone call.
