Illinois Stalking Laws

Although stalking has only relatively recently been characterized as a criminal offense within the U.S., all 50 states now have some type of anti-stalking law on the books. These laws make it a crime to intentionally and repeatedly follow someone for the purpose of harassing that person with threats of violence. Celebrities often invoke stalking laws, as do former spouses or partners, along with the use of protective orders. While we often associate stalking with unwanted contact or communication that occurs in-person, stalking can also occur over a variety of other mediums, including: the telephone, mail, email, internet messaging, social networks, etc.

In Illinois, stalking is considered a class 4 felony that occurs when someone follows or watches the victim on at least two different occasions, causing the victim to feel his or her safety or well-being is at risk in some way. Illinois stalking laws characterize aggravated stalking -- a class 3 felony -- as that which results in (or is in conjunction with) bodily harm to the victim. Aggravated stalking also includes confining or restraining the victim, as well as violating a court protective order or injunction.
