A 17-year-old boy was killed in a stabbing in Osaka’s popular Dotonbori entertainment district around midnight Sunday, the Osaka Prefectural Police said, adding that they were investigating the case as a homicide.

Two other 17-year-old boys were also taken to a hospital after being stabbed. One remains in critical condition and unconscious, while the other was also seriously injured.

About 10 hours after a suspect fled the scene, police arrested 21-year-old Ryoga Iwasaki over the stabbings.
