If you are in immediate danger, call 911. Apart from that, there are several steps in handling a violation. If an officer responds to you and finds that probable cause exists, he can arrest the suspect for the violation without a warrant. The officer can also leave the scene and attempt to locate the suspect and place him under arrest. The officer can also obtain a warrant for the suspect and arrest him later. The victim can also go get a warrant for the violation, or the victim can obtain a show cause for the violation from the clerk's office.
