We are asking for your help to locate wanted woman Ying Li.

Li, 33, is wanted in connection with reports of the production of cannabis and modern slavery in Sheffield, in addition to immigration offences.

Officers executed a warrant at an address on Fort Hill Road on 15 April and found a cannabis factory and two people who are believed to be victims of modern slavery. They are being appropriately safeguarded.

We believe Ying is still in the UK and has spent time in Sheffield this year. She has previously lived in Bournemouth.

We are keen to speak to anyone who has seen or heard from Li or knows where she may be staying.

She is described as an east Asian woman of a slim build and around 5ft 4ins tall, with straight dark brown hair.

If you see Li, please do not approach her and instead dial 999 immediately.

If you have information which could help us find her, you can report online or by calling 101. Please quote investigation number 14/70547/25 when you get in touch.

We understand that not everyone wants to speak directly to police. If this is you, please be aware that you can report information completely anonymously to the independent charity Crimestoppers by calling 0800 555 111 or by visiting their website.

You will not be asked to provide any details and no one will know you have contacted them.
