The police have not been notified of the case, but are taking all measures and actions within their jurisdiction.
Family friends who confirmed the young man's death say that everyone is in shock, and that no one has any information that the young man was suffering from anything.
By chance, an experienced emergency medicine doctor was also playing football and immediately provided first aid, but unfortunately the young man died, even though the ambulance arrived within minutes of the call.
An autopsy should show the cause of death.
