British Transport Police (BTP) is appealing for information after a couple engaged in sexual activity in a lift at Shrewsbury rail station.
Investigating officers have released CCTV images of two people they would like to speak to in connection with the incident, which occurred around 7.25pm on Saturday, September 28.
The station is used by hundreds of Montgomeryshire residents every day.
PC Kirk Smith said: “A man and a woman were seen to enter the lift which connects the station’s main subway and ticket barriers to platforms four through to seven. They remained in the lift for more than 10 minutes and, during this time, the woman performed an indecent act on the man.
“This is particularly concerning, as the station was very busy at the time and other passengers could have entered the lift at any time.
“We have conducted a number of enquiries and isolated CCTV images of a man and woman we believe may have important information in relation to this incident.
“If you recognise either individual, or have any information that could assist the investigation, I would urge you to contact police.”
Anyone with information should contact British Transport Police on 0800 40 50 40 quoting background reference B8/WQA of 22/10/2013. Information can also be passed to the independent charity Crimestoppers on 0800 555 111.
