A 38-year-old man was arrested on suspicion of taking indecent photos of young girls at a bus station in Shrewsbury, Shropshire on 13 August.
Police say he was taking pictures of the children using a mobile phone.
Speaking today, a spokeswoman for West Mercia Police told Amateur Photographer: ‘He remains on police bail while enquiries continue.’
Police say the man’s phone has been sent away for high-tech analysis, which takes time to complete.
A member of the public initially reported the man to security staff.
Last month police appealed for the woman to contact them as the security officer involved did not take down her details.
However, today police said that the woman has not come forward.
The alleged offence occurred at around 3pm on 13 August.
