If you suspect it is a counterfeit, please send it to the National Crime Agency (NCA) using the NCO1 form and guidance on your force’s intranet.
The NCA is responsible for coordinating law enforcement activity on counterfeit crime in the UK. It can advise you on your investigations. Call them on 0370 496 7622.
