“What we can say for certain is if there needed to be an example of the utter senselessness of knife crime, then this is it; four males are in hospital, and at this stage we cannot say how serious their injuries are. It is beyond comprehension.
“I would like to offer my reassurance to the community that officers are responding robustly; we remain at the scene and have also requested additional resources from the Territorial Support Group and Violent Crime Taskforce to patrol the area.
“Additionally, a Section 60 has been authorised from 18:30hrs to 09:30hrs on Friday, 17 August, providing officers with powers to deter any further potential trouble.
“I would urge anyone who witnessed this incident to call police and tell us what you saw; if you are concerned or worried about speaking to police, I can assure you your information would be treated in the strictest of confidence…”
Polices are appealing to any witnesses or anyone with information is asked to call police on 101 quoting CAD 5391/16 Aug or contact Crimestoppers anonymously on 0800 555 111.
