Hampshire Police are investigating an altercation between Cardiff City defender Krystian Bielik and a Portsmouth supporter during Portsmouth's 2-0 Championship win at Fratton Park on Saturday. The incident occurred late in the second half as Bielik went to retrieve a ball from the crowd, sparking a physical confrontation that drew players into the fray and prompted an immediate police investigation, which matters given the safeguarding concerns involving a young fan.

Police confirmed they are looking into a reported common assault on a teenage boy, while social media clips appeared to show Bielik grabbing the fan around the upper body; Cardiff's head coach said Bielik "got slapped in the face". A separate fan threw a ball at Cardiff defender Perry Ng's head, and both supporters were ejected from the ground. Portsmouth's head coach apologised to Cardiff's players, the club called it a safeguarding matter under joint investigation with police, and the FA said it will review the referee's report before deciding on any further action.
