A woman was sexually assaulted inside a B&M store, police said as they launched a CCTV appeal.
The victim was allegedly approached and touched from behind by a man at Middleton Grange Shopping Centre in Hartlepool.
Officers have now shared a picture of a man they wish to speak to whom they believe may have information.
He is photographed wearing a suit and dark tie and coming up an escalator at the shopping centre, which welcomes some 85,000 visitors per week.
The man is shown holding an unknown object in his hands, although it is unclear whether he is a store employee or a visitor.
