An investigation has been launched after a mixed race family were subjected to abuse on a train.
The incident happened on a Dundee to Aberdeen service just after 6pm on Saturday.
A man shouted racially offensive comments at a 29-year-old man and his 43-year-old wife, according to British Transport Police.
The couple, who were travelling with their young daughters aged 11 and six-months-old, were left shaken and extremely upset by the incident.
The suspect, described as being in his late fifties, 5ft 5in tall and wearing a brown jacket, got off the train at Montrose station.
Police are now reviewing CCTV footage, which has not been released, in an attempt to identify the man.
Detective Constable Derek Alexander, the officer in charge of the inquiry is appealing for witnesses to come forward.
He said: “This was a completely unprovoked incident which has really affected the family and I am anxious to trace anyone who has information which can assist our enquiries and urge them to get in touch.”
