And these are the police powers they have to arrest you for breach of the peace
Legal framework and legislation | College of Policing
Breach of the peace gives police powers to intervene and/or arrest when an individual causes harm, or appears likely to do any of the following.
- Cause harm to a person.
- Cause harm to that person’s property, in the person’s presence.
- Put that person in fear of such harm being done through an assault, affray, a riot, unlawful assembly or other disturbance
Police officers may take reasonable action, including arrest, to stop a breach of the peace, or to prevent one that the police officer reasonably anticipates will occur imminently. Reasonable action may also be taken where a breach of the peace has been committed and where it is reasonably believed that a recurrence of the breach is threatened.
Police action should target the persons responsible for the breach of the peace. Action taken that is not directed at the person committing the breach will generally be unlawful.
The guiding principle is that lawful conduct will rarely, if ever, be other than reasonable. Conversely, a violent reaction to the lawful conduct of others will rarely, if ever, be other than wholly unreasonable.
Where there is a reasonable belief that there are no other means to prevent a breach of the peace, the lawful exercise by innocent third parties of their rights may be restricted by the police. This is a test of necessity, which can only be justified in truly extreme and exceptional circumstances.
Before the police can take any steps that restrict the lawful exercise of rights by innocent third parties in any way, they must take all other possible steps – including making proper and advance preparations – to ensure that the breach, or imminent breach, is prevented and that the rights of third parties are protected.
It's important to know your rights as well as police powers.
And it's wrong that the police can arrest someone because they feel that the presence of that person could lead to someone committing violence or harm against them
It's wrong in this case. And it's wrong in other cases
