A man armed with a knife has run amok outside a shopping centre in a Japanese city near Tokyo, killing one person and wounding seven others.
The suspected knifeman had been on a police wanted list
Police in Tsuchiura, 50km (31 miles) north-east of the capital, arrested the suspect, who was already wanted over a separate killing last week.
The 24-year-old reportedly told them he had "just wanted to kill anyone".
Japanese media reported scenes of chaos during Sunday's attack as bloodied victims tried to escape.
Correspondents say violent crime is relatively rare in Japan except for killings by crime syndicates, although there have been concerns about a recent rise in street violence.
The suspect, identified as Masahiro Kanagawa, allegedly stabbed his victims in a hallway connecting the mall with a railway station.
At least one of the injured was said to be in a serious condition.
The man killed was named as 27-year-old Takahiro Yamagami.
After the attack, the suspect phoned police to say he was the perpetrator and officers subsequently overpowered him, Japan's Kyodo news agency reports.
Police confirmed that they had been searching for Mr Kanagawa since a 72-year-old male resident of Tsuchiura was stabbed to death on Wednesday.
Eight police officers had been on duty at the station at the time of the mall attack, and police issued an apology for failing to prevent it.
"It was extremely regrettable that we could not prevent the attacks that caused casualties, despite our utmost effort to avoid secondary crimes [by the wanted suspect]," police official Takashi Ishii was quoted as saying by the Associated Press.
