Threats of violence describes words, messages or conduct communicating an intention to inflict unlawful physical harm and causing the recipient to fear it will be carried out. It is a descriptive expression used across criminal, public order, harassment, communications and domestic abuse contexts rather than a single defined term, though specific offences exist.Key examples include: England & Wales and Northern Ireland-threats to kill (Offences Against the Person Act 1861, s16); fear or provocation of violence (Public Order Act 1986, s4); harassment and stalking causing fear of violence (Protection from Harassment Act 1997, incl ss2A, 4, 4A); malicious or threatening communications (Malicious Communications Act 1988; Communications Act 2003, s127); blackmail (demands with menaces) (Theft Act 1968, s21; Theft Act (NI) 1969, s20); coercive or controlling behaviour in domestic abuse (Serious Crime Act 2015, s76). Scotland-threatening or abusive behaviour (Criminal Justice and Licensing (Scotland) Act 2010, s38); threatening communications (2012 Act, Part 2); domestic abuse (2018 Act); extortion at common law. Ireland-threats to kill or cause serious harm (Non-Fatal Offences Against the Person Act 1997, s5); harassment (s10); harmful/threatening communications (Harassment, Harmful Communications and Related Offences Act 2020); blackmail (Criminal Justice (Theft and Fraud Offences) Act 2001, s17).Threats alone may constitute common assault where immediate unlawful violence is apprehended (E&W/NI); in Scotland similar conduct is typically prosecuted under s38. Practically, threats support arrest, bail conditions, restraining or non-molestation orders, interdicts and protection/safety orders.
