Detectives have issued CCTV footage to help trace a number of offenders who are believed to have carried out four robberies in the Bestwood and Top Valley areas of Nottingham over the weekend.

The first incident occurred outside the Co-op supermarket in Beckhampton Road at around 11pm on Friday.

Three people were stopped by the group of around ten males and females, a number of whom threatened and assaulted them, with at least one of the victims sustaining cuts to the face from what is believed to be a knife. The victims’ mobile phones and a rucksack were stolen.

The two main offenders in this incident were both white males believed to be in their late teens. One was stockily built, had dark hair and wore a blue top. The other was around 6ft tall, of skinny build, and wore a black puffa  jacket.

CCTV footage of a group of six males and females seen at this location at around the time of the offence has been issued by police as part of the investigation.

The following day, a similar incident occurred in Old Farm Road, Top Valley, at around 6.30pm. Two men were threatened with knives and had their mobile phones stolen by two offenders.  (Incident 734 of 16 May).
