Stalking

Stalking (from Middle English stalk: from Old English bestealcian; akin to Old English stelan to steal) is a legal term for repeated harassment or other forms of invasion of a person's privacy in a manner that causes fear to its target.

According to the United States' National Center for Victims of Crime, one out of every 12 women and one out of every 45 men will be stalked during their lifetime.citation needed]
