What action is typically necessary when a "Fight in progress" call is received?

When a "Fight in progress" call is received, the immediate deployment of units is essential to ensure public safety and to prevent further escalation of the altercation. Responding officers must arrive at the scene as quickly as possible to assess the situation and take control. Time is a critical factor in these situations, as delays could lead to injuries or increased chaos among those involved in the fight or bystanders.

While preparation for a follow-up call, notifying additional personnel for standby, and commencing interrogation of witnesses may be part of the overall incident management process, they are not the immediate actions that need to take place. The priority must be to send available law enforcement or emergency units to the scene to manage and resolve the ongoing conflict effectively. Thus, immediate deployment of units is the correct action to take when such a call is made.
