Indecent assault on train between Inverness and Aberdeen
Witnesses are being sought after a 22-year-old woman was indecently assaulted as she worked on a train between Inverness and Aberdeen.
The hospitality staff member was grabbed by a man on the 17:15 service on Friday.
It is believed he was part of a group which got on at Thurso and got off in Aberdeen.
British Transport Police (BTP) said the man was described as being bald, in his 40s and of heavy build.
He was wearing a red shirt and a black jacket, and was said to have been drinking.
CCTV will be viewed in an attempt to identify the man responsible.
Det Con David McAllister, the BTP officer in charge of the inquiry, said: "The woman was left distressed by the incident and members of rail staff should be able to go about their duties without encountering such unsavoury and unwelcome behaviour.
"I am appealing for anyone who was on the train or at any of stations and has any information which could help the enquiry to get in touch."
BTP can be contacted on 0800 40 50 40 or by texting 61016 - quoting reference B of 8/10/2014.
