A Domestic Disturbance call is sent out by law enforcement dispatchers at random times. You will hear a radio call as well as text on your chat to indicate when a Domestic Disturbance comes through. Type /respond to acknowledge the call and the dispatcher will send you the location of the response. 

Turn on your lights and sirens and drive as fast as you can to the call. If you are the first officer at the scene, you will receive a reward. 

Type /cancel at any time during the mission to cancel it.
