In a week that has already seen a major roller coaster related accident, Cobra at Tivoli Friheden in Aarhus, Denmark derailed late Friday. Four people were hospitalized suffering broken bones. The cause of the accident is unknown, however it is believed that several bolts were replaced hours before the derailment.

The ride was the first roller coaster from the company Ride Tek - I think it’s pretty safe to say it’ll be their last too.
