FYI, still think its ridiculous he might go to prison but if guilty.....
1. A person is guilty of affray if he uses or threatens unlawful violence towards another and the person's conduct is such as would cause a person of reasonable firmness present at the scene to fear for his personal safety.
2. Where two or more persons use or threaten the unlawful violence, it is the conduct of them taken together that must be considered for the purpose of subsection (1)
3. For the purposes of this section a threat can not be made by the use of words alone.
4. No person of reasonable firmness need actually be, or be likely to be, present at the scene.
5. Affray may be committed in private as well as in public places.
A person suspected of affray is subject to arrest, can be tried either in a Magistrates Court or Crown Court, and faces three years imprisonment and/or a fine on indictment; six months imprisonment and/or a fine summarily.
