A man took photographs of a woman as she tried on clothes in an Asda changing room.

The voyeur is reported to have snapped a picture of her over the top of the cubicle on his mobile phone.

She alerted supermarket staff but the man left the building.

The incident is alleged to have happened in a supermarket in Thames Way, at about 10.50am on Sunday, September 11.

Officers have been carrying out inquiries but the offender remains at large and today police released an image of a man they believe may be able to help them.

Anyone who recognises the man in the CCTV image is asked to call the appeal line on 01474 366149 quoting reference XY/35927/16, or Crimestoppers anonymously on 0800 555111.
