12 CCTV pictures show people caught on camera South Yorkshire police are currently trying to trace

These 12 CCTV pictures have been issued by South Yorkshire Police in a bid to trace people as part of criminal investigations

Police investigating 12 crimes have released CCTV pictures over the last month - all as part of their investigations into incidents in Sheffield and South Yorkshire

They have been taken from cameras which capture images out on the streets and parks of Sheffield and South Yorkshire, with many of them taken from CCTV cameras. All have been published in connection with ongoing South Yorkshire Police appeals.

The force is currently displaying the pictures online. Those in the pictures are not necessarily suspects, but could also be potential witnesses.

Do you recognise any of the people in the pictures? Police want to speak to them in connection with crimes ranging from assaults to thefts.

If you recognise anyone, you can contact South Yorkshire Police online by logging onto www.southyorks.police.uk/contact-us/report-something/

You can also phone South Yorkshire Police on 101. In each case, we have included the police incident number or crime number in the picture caption, and this should be quoted in any message to police.

Alternatively, if you prefer not to give your personal details, you can stay anonymous and pass on what you know by contacting the independent charity Crimestoppers. Call their UK Contact Centre on freephone 0800 555 111 or complete an online form on the Crimestoppers website.
