Eight members of the gang, who are suspects in the murder of a Karate champion and an owner of a nightclub in Anuradapura, has been arrested by the Anuradhapura police, the Police Spokesperson ASP Ruwan Gunasekara says.
The preliminary investigations into the murder have disclosed that a personal dispute between the suspects and the nightclub owner had led to the incident, according to the police.
The incident had occurred at the night club down Muditha Street in Anuradhapura at around 11.45 on Sunday.
The group of about 15 masked men who entered the night club had killed its owner by assaulting him with clubs and sharp objects.
The 57-year-old victim succumbed to his injuries after admitting to the Anuradhapura Teaching hospital. Three employees at the night club have also been admitted to the same hospital, following the attack, the police added.
