Dutch police have arrested a fourth soccer player suspected of involvement in a brutal beating that left a volunteer linesman dead after a youth match last weekend.
Prosecutor Brigit Haan says police arrested a 16-year-old boy Thursday night on suspicion of involvement in the attack.
The latest arrest comes on the eve of a weekend in which all amateur matches have been canceled nationwide to mourn 41-year-old Richard Nieuwenhuizen. He was assaulted Sunday after officiating his son's match between Almere club Buitenboys and Nieuw Sloten of Amsterdam. He died a day later with his family at his hospital bed.
Three other Nieuw Sloten players were arrested Monday. They're being held on suspicion of manslaughter, assault and public violence.
