Police are hunting two men over disorderly behaviour and criminal damage on a train travelling through South Yorkshire.
British Transport Police said two men travelling on a Northern Rail train between Meadowhall and Thurnscoe were abusive towards a conductor after she reprimanded one of them for spitting.
The men were then said to have started swearing and using threatening language.
They also sprayed graffiti onto a number of train windows.
PC Helen White said: “The conductor of the service approached two young men, one of whom had spat out of the door at Swinton station, and reprimanded him.
“The pair then became abusive towards the conductor, swearing and using threatening language, which made her feel intimidated.
“When the doors were released the pair left the train and went on to spray black paint on the windows. One of them then walked towards the conductor spitting and swearing at her.
“It was later discovered that the same graffiti had been sprayed inside the toilet.
“This member of staff was simply doing her job. No-one should have to be subjected to such intimidating behaviour.”
Anyone with information about the incident at around 3.30pm on Wednesday, September 16 should call British Transport Police on 0800 405040.
