A new Policing & Crime Act has come into effect which will make the use and possession of fireworks, flares and other forms of pyrotechnics illegal in England and Wales.
As NME reports, those detained at the security checkpoints of festivals in those parts of the UK could face up to three months in jail or a fine.
In a blog post by solicitor Alex Chapman, pyrotechnics are defined as "an article that contains explosive substances, or an explosive mixture of substances, designed to produce heat, light, sound, gas or smoke, or a combination of such effects, through self-sustained exothermic chemical reactions".
Matches are exempt from the law despite the above description and it’s noted that most arrests of this kind will take place at festivals’ security checkpoints as it is difficult for security to track down those using flares amongst crowds.
