Japanese police on Thursday arrested three Vietnamese nationals for allegedly killing a fellow citizen whose body was found late Sunday on a street in Osaka, Kyodo News reported.
The arrestees are Do Tuan Hau, 30, his wife, and another man, the news agency said.
The police are searching for three other suspects as security footage shows a group of six people armed with knives and a baseball bat before the attack, it said.
The footage shows this group chasing and surrounding a man before stabbing, battering and stomping on him on a street in Ikuno Ward on Sunday.
It also shows the attackers leaving the scene as if nothing had happened.
The man, who was pronounced dead after being taken to a hospital, sustained several stab wounds to the chest and abdomen, Kyodo News reported.
He has been identified as Nguyen Trong Tuan, 25, according to Vietnam’s Ministry of Foreign Affairs.
Japanese police suspect the group of six people was also involved in the attacks nearby on two other men, who are Tuan’s friends.
They are now under treatment for severe wounds at a hospital in Osaka but were not in a life-threatening condition, Kyodo News said.
It quoted the police as saying that Do Tuan Hau and his wife are the owners of a restaurant near the area where the attacks happened and were in conflict with Tuan over money.
Hau reportedly told the police that he “did not mean to kill Tuan.”
