Boys on bicycles 'surfed' train at Kingussie

The teenagers were filmed holding onto the train earlier this month

Two teenage boys on bikes have been filmed on CCTV holding onto a passenger train as it pulled out of a Highlands station.

British Transport Police described the behaviour in Kingussie earlier this month as "surfing".

The boys grabbed hold of handles on the doors of a carriage and were pulled along the platform.

BTP said the incident happened at about 19:30 on 8 January and appealed for information.

Constable Matt O'Neill said the behaviour was rare.

But he added: "It is an incredibly dangerous practice.

"I cannot underestimate how foolish it is to mess about around trains and stations.

"As well as potentially delaying trains you could be seriously injured."
