British Transport Police (BTP) detectives are appealing for information after a man performed an indecent act in front of a female passenger on a train between Cardiff and Newport.
Officers have released this CCTV image of a man they believe may have key information which could assist their investigation.
Investigating officer PC Jon Childs said: “The victim, a 48-year-old woman who was travelling alone, boarded the 6.23pm Cardiff Central to Cheltenham Spa service at Cardiff.
“After taking her seat, a man came to sit directly opposite her. This man then exposed himself throughout the journey and performed an indecent act, all while looking directly at the victim.
“The incident lasted about ten minutes, until the man left the train at Newport.
“This was a sustained act which had a significant impact on the victim, who was visiting the area for the first time.
“Fortunately this type of incident is rare on the rail network, but understandably the victim was left extremely shaken and upset by what she had been forced to witness.
“I am now calling on the public to help bring this man to justice.”
Having viewed CCTV footage, officers have identified a man they would like to speak to in connection with the incident, which happened on Sunday, November 27 2011.
“The man is in his mid to late 60s and was wearing a brown overcoat and checked shirt,” said PC Childs.
“We are anxious to speak to this individual as we believe he may have key information that could assist us in our investigation.
“If you recognise the man pictured, or have any information about the incident, I would urge you to contact police.”
