Police investigating the disorder following a rave in Croydon have released eight new images of people they would like to trace.
The images are of people who were in and around the site of the rave at a disused sorting office in Cherry Orchard Road in the early hours of June 15.
South Area Commander Simon Letchford said:
I am appealing for anyone who recognises these people, or has information about the disorder, to come forward and speak to police. The behaviour of some of those attending this illegal rave and the direct attacks on officers who were there to maintain public safety is completely unacceptable. Twenty people have now been arrested and I would like to thank the public for their support.
I am particularly keen for anyone who took images or video on mobile phones of the events in and around the area to provide these to police. They may contain vital evidence to help track down those responsible for this violence.
So far, a total of 20 people have been arrested in connection with the event, nine of whom were arrested during the event.
Rio Andrew, 15, was taken to hospital, after falling ill at the event. A 19-year-old also taken ill at the rave has now been discharged from hospital.
