Japanese police have found nine bodies, including two with their heads severed and dumped in a cool box, in a flat in the Tokyo suburbs, media reported on Tuesday.
Police have arrested 27-year-old Takahiro Shiraishi, who lives in the apartment in Zama, south of Tokyo, public broadcaster NHK said.
A police spokesman could not immediately confirm the reports.
Authorities had been investigating the disappearance of a 23-year-old woman and discovered a connection between her and Shiraishi.
According to Jiji Press, police found the two heads inside a cool box at the entrance of the apartment on Monday before making the grisly discovery of the other bodies inside on Tuesday.
Police confirmed to AFP they had arrested 27-year-old Takahiro Shiraishi, who lives in the apartment in the quiet residential neighbourhood of Zama.
Police originally found two heads inside a cool box at the entrance to the apartment before making the grisly discovery of the other body parts, according to Jiji Press.
“During the course of the investigation, the heads of nine bodies have been discovered” inside various coolers and containers in the apartment, private TV network TBS said.
For the time being, police arrested Shiraishi on a charge that he dismembered one body and placed it inside a cooler, a charge that he was not contesting, according to a spokesman at Tokyo Metropolitan Police.
“He has said ‘I dismembered a body and placed it inside a cooler and poured cat litter over it. It was meant to hide the body that I killed and to hide evidence’,” the spokesman told AFP, declining to elaborate.
