Anti-Social Behaviour
What is considered anti-social behaviour (ASB)?
Anti-Social Behaviour is defined as 'behaviour by a person which causes, or is likely to cause, harassment, alarm or distress to persons not of the same household as the person' (Anti-social Behaviour Act 2003 and Police Reform and Social Responsibility Act 2011).
But there are different types of anti-social behaviour, which can fall into two categories, Criminal Anti-social Behaviour and Environmental Anti- Social Behaviour.
Here is a good breakdown on Police UK of what constitutes Criminal ASB and Environmental ASB. It's important to know the difference, as it indicates who you should report the problem to.
