Train services are facing disruption due to a 'passenger disturbance'.

ScotRail has said due to an incident onboard a train at Johnstone in Renfrewshire, services in the area may be subject to alterations.

The rail firm has warned passengers that disruption to services may still be 'ongoing' until staff and trains are back in position.

It is unclear what the incident was, however, we have contacted the British Transport Police for comment.
