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 2012.
At the time, police said he had been seen taking pictures of the children using a mobile phone.
A spokeswoman for West Mercia Police today told Amateur Photographer (AP) that the man - who has not been named, or charged with an offence - has been rebailed until 13 May while officers continue to make enquiries.
The man is expected to attend Shrewsbury Police Station on the same day.
In September, West Mercia Police told AP they had sent away the man's phone for analysis.
The police spokeswoman today declined to reveal the outcome of the tests.
A member of the public initially reported the man to security staff at the bus station.
The alleged offence occurred at around 3pm on 13 August.
