South Yorkshire Police are hoping these pictures can help them with investigations which have been going on through October and November.
The 12 images have been issued by officers as part of enquiries ranging from serious assaults to burglaries, and are believed to be of people who can help with those investigations.
Most of the incidents happened in Sheffield, but we have also included some from other parts of South Yorkshire.
They have been taken from cameras which capture images out on the streets of Sheffield, with many of them taken from CCTV. All have been published in connection with ongoing South Yorkshire Police appeals.
