The British Transport Police (BTP) has published a photo of a man they wish to speak to in connection with an ongoing investigation into an incident on a train in Renfrewshire.
Officers are hoping the man pictured can assist them with their enquiries relating to an incident that occurred on board a service between Glasgow Central and Johnstone railway station on Wednesday, March 1.
They are urging the man shown or any members of the public who recognise him to contact them.
