Chief Sean Riggin said he was proud at how his officers responded.

'They kept an angry group at bay, without arresting or fighting an unnecessarily hostile crowd, and then disregarded their own safety to carry the patient to the ambulance while a hostile stood by and berated police without cause,' Riggin said.

'I stand proudly behind my officers who were confronted by a crowd who seemed eager to engage in a confrontation with police over an issue the officers cannot control, ambulance response time.

'I'm disappointed that all the hard work of these officers to engage in our community is thrown aside by a few reckless individuals who seemed determined to fight police or start a riot. The officers did a professional job in spite of the actions of several who sought to create a dangerous and chaotic environment and I am proud of them'
