Police have arrested five people suspected of a grenade attack on the family house in Serbia of Dragan Stojkovic, the coach of Japanese team Nagoya Grampus and a former Red Star Belgrade and Marseille player.
Police said Friday the group includes prominent former football official Aca Bulic, who is suspected of organizing the attack. They say one suspect remains at large.
No one was injured in the hand grenade attack in February in the southern city of Nis, but it left a hole in the yard near the house. Stojkovic's mother, Desanka Stojkovic, was inside.
Police did not say why Bulic allegedly organized the attack.
Red Star fans have accused Stojkovic of profiting from the sale of Red Star players while serving as the club's president in 2005-07.
