Inverkeilor derailment: Police seek four youths
Officers from British Transport Police investigating the derailment of a train in Angus have said they are keen to trace a group of four youths.
The group were seen near the derailment site at about 19:30 on Saturday, 3 November.
The next day, CrossCountry Trains' 08:04 service from Edinburgh to Aberdeen came off the rails at Inverkeilor.
BTP said an obstruction appeared to have been placed on the tracks.
Officers said the youths ranged from 5ft to 5ft 6in tall. One was wearing a grey or light coloured hooded top and trousers.
Det Ch Insp Iain Miller, the officer in charge of the inquiry, said: "The youths were seen walking towards Bryanton House just off the A92.
"This would have been prior to the bonfire at Inverkeilor, the night before the incident occurred. It is important to trace these youths in order to eliminate them from our enquiries."
The force is also appealing for anyone who attended the bonfire to come forward if they have not already done so and officers are asking for anyone who took photographs on the evening to get in touch.
The rail industry has put up a £25,000 reward for anyone who provides information which leads to the arrest and conviction of those responsible for causing the derailment.
There were 36 passengers on board the train, which was travelling at 76mph, when it came off the tracks at about 09:45 on Sunday, 4 November.
None of the passengers were hurt, but the 49-year-old driver suffered a minor head knock and was treated by ambulance crews.
