The Protection from Harassment Act 1997 (PHA) was introduced to target stalking. For the most part, Parliament had strangers in mind, whether physically following a victim and/or persistently giving them unwanted attention. As is often the way, enforcement of the Act evolved from those early intentions. Now, the vast majority of prosecutions involve people who know each other, one of them reporting that they are the victim of a course of conduct which amounts to harassment by the other, and which that person knew or ought to have known caused them harassment alarm or distress. The basic offence, section 2 of PHA, is a summary-only offence (meaning it can only be tried in the Magistrates’ Court) but the more serious offences of harassment putting people in fear of violence (section s4 of PHA), or stalking involving fear of violence or serious alarm or distress (section 4A of PHA), can be tried in the Crown Court and both incur up to five years imprisonment.
