A gang clash at Christchurch Hospital's Emergency Department is being investigated.
Police were called just after 8pm yesterday, with reports of an altercation between four Mongrel Mob members or associates.
One person was assaulted, and another taken into custody.
City Councillor Aaron Keown says it speaks to a wider community issue.
"With our growing gang situation that needs to be knocked on the head, I look forward to the Government enforcing the no-patches issue. Certainly in hospitals, you shouldn't be allowed to colour up or patch up when you come in."
