The British Transport Police are calling on the public to help identify a man after two teenage girls were the target of inappropriate remarks.
The offence happened as the pair travelled on the 12.15pm Skegness to Nottingham train on Saturday, August 22.
PC Joshua Dunn, investigating, said: “Both girls, aged 16, were travelling together on the train when a man boarded at Grantham and sat down next to them before making a number of inappropriate comments which made them feel understandably uncomfortable.”
Officers have followed a number of lines of enquiry and are now issuing CCTV images of a man they wish to speak to in connection with the incident, as they believe he may hold key information which will assist the investigation.
Anyone with information is asked to contact British Transport Police on 0800 40 50 40, or text 61016, quoting reference MSUB/B8 of 5/10/2015.
Information can also be passed anonymously to the independent charity Crimestoppers on 0800 555 111.
