Fly posting without a permit is illegal
Cleaner Communities - Fly Posting
Fly- posting without a permit is illegal under the Highway Act 1980, the Town & Country Planning Act 1990, the Anti-social Behaviour Act 2003 and the Clean Neighbourhoods and Environment Act 2005. It makes an area messy and untidy. Most local councils have a zero tolerance policy on fly- posting.
Since the police consider the removal is an offence, someone gave a permit - who?
