Police are appealing for help to identify two men and a woman, who they want to speak to in connection with a city centre robbery.
The offence happened in Derby Market Place, where a 19-year-old student was dragged to the floor as the thieves tried to grab her handbag from her shoulder.
Two of the victim’s friends intervened but the three offenders managed to get away with the bag and ran off.
The victim, who is a university student and new to the city, was not seriously hurt but was left shaken by the robbery, which happened on September 10.
Officers want anyone who may recognise any of the three people shown in the footage to come forward. DC Tim Phillips, who is leading the investigation, said:
Witnesses or anyone with information can call Tim on 101, quoting reference 17000389038.
