Police are investigating after a man made "multiple attempts" to put his mobile phone under a schoolgirl's skirt.
British Transport Police said they believe the 15-year-old was a victim of "upskirting" at Manchester's Piccadilly Station.
Upskirting is the illegal practice of taking images under clothing without permission. Dedicated new laws came into force earlier this month.
They've released CCTV images of a man they want to speak to:
BTP said the incident happened on April 1st at around 4:30 pm.
The victim was wearing her school uniform when she was followed around the station's Sainsbury's by a male stranger, before he put his phone under her skirt and left the shop without buying anything.
Officers believe the man in the CCTV image may have information which could help their investigation.
Anyone who recognises him is asked to get in touch.
