"Stupid behaviour" by occupants of a car was captured by an unmarked police bike in Snowdonia. 

North Wales Police's Roads Policing Unit released the footage as part of Operation Darwen - a police campaign in Wales to reduce road traffic collisions. 

It shows two men hanging out of the windows of the car, appearing to be taking selfies.

A spokesperson for the Roads Policing Unit said: "Perfect example of stupid behaviour...

"Captured whilst one of our unmarked bikes was on #OpDarwen patrol in Snowdonia last Sunday.

"Car stopped and tickets issued. Stern words were also given. Their excuse - 'taking pics for Snapchat'."
