Police have released photos to help trace eight suspects they want to interview after an illegal rave ended in violence and death in Croydon last month.
They are hoping that the release of the new photos will have a similar result as a batch released on June 18, 2014 and June 27, 2014, which led to the arrest of two men for violent disorder.
A major police operation was mounted in the early hours of Sunday June 15, 2014 to shut down the rave in a disused Royal Mail sorting office in Cherry Orchard Road.
Rio Andrew, 15, of Notting Hill fell ill at the event and died later in hospital.
Party-goers launched fire extinguishers and furniture at police officers attempting to stop additional people from entering the building.
Some officers sustained minor injuries but none required hospital treatment.
Metropolitan Police South Area Commander, Simon Letchford, said: “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.’’
Detectives have also asked for anyone who may have taken pictures on their phones at the rave to contact police.
Letchford said: “I am appealing for anyone who recognises these people, or has information about the disorder, to come forward and speak to police.
“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, 20 people have been arrested in connection with the rave.
A 21-year-old man has been charged with violent disorder, drugs offences and assault on a police officer, while a second man has been charged with violent disorder and drugs offences.
Two men have received cautions for possession of Class A drugs and enquires are continuing regarding the other suspects.
Anyone with information about the suspects in the photos is asked to contact the Public Order Investigations Team on 020 8246 0076 or Crimestoppers anonymously on 0800 555 111.
