A WOMAN ticket examiner has been assaulted while working on a train.

The 35-year-old was left "extremely upset" by the incident, which happened on the 6.34pm Glasgow Central to Ayr service on Saturday.

British Transport Police (BTP) said she approached a group of men to check their tickets when one of them pulled her by the back of her head and made sexually explicit gestures.The man responsible is described as being around 6ft and of slim build. He was wearing a grey flat cap and a wax-style jacket and jeans.

He spoke with a local accent and had been drinking.

It is believed the group got on at Irvine and got off the train at Prestwick Town station.

Detective Constable Craig Jennings, of BTP, said: "Anyone who was on the train or was at either station and who may have witnessed this assault on someone just getting on with their work is urged to get in touch."

In a separate incident, a 19-year-old woman was attacked by two men on a train when she was travelling in the area of Uphall, West Lothian.

She was approached by the pair on the 10.13pm Edinburgh Waverley to Helens-burgh service on Sunday night.

BTP said words were exchanged before the victim was grabbed and punched by one of the men.

The other one spat on her.

Although shaken, the victim did not require medical treatment.

Both suspects are described as being aged about 40 and of heavy build.

Both of them spoke with Glasgow accents.

Detective Constable David McAllister said: "This was a completely unprovoked attack on a defenceless woman and I am anxious to speak with anyone who was on the train and witnessed it to come forward."
