Nottinghamshire Police have released a picture of a woman they want to speak to following an assault in Bulwell town centre on Wednesday June 13.
She is described as white, around 5ft 6ins tall, of a stocky build with blonde hair; she was wearing a checked top, blue jeans and plimsolls.
She was thought to have a Polish accent.
The force say they appreciate the photo is not very clear but hopes that it could jog a memory as the woman was pushing a double buggy with two young children in it.
If you recognise her or think you can help, you are asked to call Notts Police on 101 quoting incident number 509 of June 13.
Alternatively, you can contact Crimestoppers anonymously on 0800 555 111.
