Video of man ziplining in the Lyon metro has gone viral. For its part, the operator indicates that this type of behavior can be punished with a fine of 135 euros.

“They do this to get views on Instagram. It doesn't happen every day fortunately. But on a network which has several million trips there are always singular behaviors. It’s fun and original but it can have consequences for people if the metro brakes suddenly,” says Keolis to Le Figaro.
