25 CCTV pictures, found by South Yorkshire Police, show people cops need to speak to now over investigations

Police release CCTV footage as part of crime investigations in Sheffield and nearby towns ranging from serious assaults to thefts

These are 25 pictures showing faces, taken from pictures across Sheffield and South Yorkshire, that police are keen to trace.

Officers have taken the pictures from closed circuit TV cameras in Sheffield, as well as Barnsley, Rotherham and Doncaster, and want to find those people shown as part of investigations ranging from serious assaults to thefts.

These pictures have been released by South Yorkshire Police this year, and remain on the force’s list of appeals as officers try to solve crimes and incidents across the county.

All those pictured in this gallery appeared in appeals published by officers as part of investigations into incidents which have happened in Sheffield and South Yorkshire, ranging from assaults and robberies to anti-social behaviour.

The images have been taken from CCTV cameras and individuals covering the streets, businesses and parks of South Yorkshire

All have been published in connection with ongoing South Yorkshire Police appeals which are currently carried on the force's website.

Those in the pictures are not necessarily suspects, but could also be potential witnesses.
