Police warn that counterfeit football shirts sold during the World Cup period may pose safety risks to fans. In recent enforcement actions, authorities have seized £18 million worth of counterfeit jerseys, prompting renewed concern about the materials used in unregulated merchandise. A detective sergeant involved in multiple raids says fake kits can be dangerous because they may be more flammable than legitimate apparel. The officer also raises concerns about dyes and other components used in counterfeit clothing, which may not meet safety standards and could irritate or affect skin. The warning highlights that counterfeit goods are often produced outside official quality controls, meaning their chemical composition and fire-retardant properties are unclear. Authorities’ message focuses on consumer safety and the potential consequences of wearing or handling such items, rather than on any performance or branding issues. The reports describe the seizures as part of efforts to disrupt the counterfeit market and underline that the risks extend beyond legal concerns.
