Harassing Calls

It is the police department’s intent to encourage responsible use of telecommunications devices and service providers. There are steps that you can take to minimize unwanted communication before they even happen. Some of the unwanted communication from businesses, marketers, or spammers is particularly easy to prevent.

Michigan Law

• Threatening physical harm or damage to any person or property.

• Falsely and deliberately reporting a person has been injured, has suddenly taken ill, has suffered death, or has been the victim of a crime or an accident.

• Using vulgar, indecent, obscene, or offensive language or suggesting any lewd or lascivious act in the course of a conversation or message.

• Repeatedly initiating a telephone call and, without speaking, deliberately hanging up or breaking the telephone connection as or after the telephone call is answered.
