2. Assault
Officers need to trace these two men in connection with a violent assault in Chesterfield. At around 4am on Sunday October 10 a 39-year-old man was assaulted in Holywell Street outside Vibe Bar. He was punched and then kicked to the head when he fell to the floor. Police say a woman may have witnessed what happened but has yet to speak to the police. She had long dark hair and wore a stripy top - she waited to speak to officers at the scene but left before officers were able to talk to her. There was a queue of people waiting to get into Vibe at the time and there may be witnesses who have yet to come forward. Photo: Derbyshire Police
3. Attempted burglary
Police say this man was in the area of Sheffield Road, Sheepbridge, when two businesses there were victims of criminal damage and an attempted burglary. Officers are keen to him in relation to the incidents. The premises were targeted overnight between 5.30pm on August 17 and 8am the following day. Photo: Derbyshire Police
