Since 2023, serious threats have been made against the winger via social media. Detectives from the Rotterdam-Zuid police, who specialize in football-related crime, have started an investigation into the threats. Because various football investigations converge with these specific detectives, they have extensive knowledge and experience on the subject, and any connections between different investigations become visible. The investigation led to the 18-year-old from Dordrecht who was arrested in his home on Thursday morning. The man was released after questioning. Once the file is complete, it will be handed over to the Public Prosecution Service, and the public prosecutor will assess the case. The suspect has been given a restraining order and an area ban for places where Lang frequently visits.

Threats can have a huge impact on a victim and those around them. It can evoke fear or aggression and thus has a significant influence on someones life. It is a criminal offense to threaten with violence, manslaughter, but also to threaten with assault, rape, or arson. The form in which the threat occurs is not important. A text message, an email, a response via social media, or verbally; all are equally punishable. Even expressing threats via anonymous social media accounts does not mean you can get away with it. The police have various ways to uncover who is behind a particular account.
