Police are appealing to walkers for help in tracking down vandals on Wales’s highest mountain.

An excavator belonging to Snowdonia National Park Authority had its windows smashed on Saturday afternoon on Snowdon.

The digger was being used on the Llanberis Path as part of the authority’s maintenance works.

North Wales Police said the incident happened between 3pm and 6pm on 19 April, half-way up the mountain. The excavator has had to be removed from the hill for repair.

A police spokesperson said: “Due to the good weather on Saturday afternoon police are hoping somebody may have witnessed the incident as it was very busy in the area.”

Anyone who was on Snowdon at the time and has information is asked to contact North Wales Police on 101, quoting reference RC16040417. Members of the public can also use the force’s live web chat to provide information.
