Dutch police have arrested a fourth young footballer suspected of involvement in a brutal beating that left a volunteer linesman dead after a youth match last weekend.
Police arrested a 16-year-old boy on Thursday night on suspicion of involvement in the attack, prosecutor Brigit Haan said.
The latest arrest comes on the eve of a weekend in which all amateur matches have been cancelled nationwide as a mark of respect for 41-year-old Richard Nieuwenhuizen, who was assaulted on Sunday after officiating a match his son was playing in between Almere club Buitenboys and Nieuw Sloten of Amsterdam. He died a day later with his family surrounding his hospital bed.
Three other Nieuw Sloten players were arrested on Monday and are being held on suspicion of manslaughter, assault and public violence.
