Thames Valley Police has released a CCTV image of a man who might have information about a sex offence in Bletchley.
An offence took place at Asda in Bletcham Way on Tuesday at about 4.45pm.
The victim, a 28-year-old woman, was trying on clothes in the fitting rooms of the store when she noticed a hand holding a phone appear under the curtain.
She shouted out, and the suspect ran out of the changing rooms into the store.
“We are appealing for the man pictured in this CCTV image to come forward as he may have information vital to our investigation into this incident,” Investigating officer, PC Rebecca Maylin said.
“If you have any information about the incident, please call the 24 hour Thames Valley Police enquiry centre on 101.”
