Do you recognise this man who police want to speak to in connection with shopping centre sex assaults?
The offence took place at about 4.10pm on Sunday, 8 May, in Poundworld, in Hale Leys Shopping Centre.
Three girls, under the age of 13, were looking at items in the shop when two of them were touched over their clothing.
They immediately left the shop to contact their families. It is possible there was another, adult female, victim who has not formally contacted police.
Officers would like to speak to the man in the CCTV image because he might have vital information that can help their investigation.
