Last August, the six suspects, including gang member Hisataka Shiraishi, 32, allegedly worked together to confine and beat the former manager, 28, inside a vehicle and residence.
The victim suffered at least one broken rib in the assault, police said.
“We didn’t force him into the car,” Shiraishi commented to police.

According to police, Shiraishi is involved in operating the cafe, located near JR Nishi-Nippori Station in Arakawa Ward.
In carrying out the beating, the suspects used a hammer. Afterward, they took the victim to the hospital on two occasions.
The incident took place after the victim quit his position as manager after he began dating one of the female employees at the cafe.
