Police on Thursday searched one of Japan's biggest maternity clinics, Yokohama's Hori Maternity Hospital, where nurses were allegedly allowed to illegally conduct intrauterine examinations on a pregnant woman, who later died at another hospital after developing complications from giving birth.
Investigators questioned hospital owner Kenichi Hori and several employees, police sources said.
Hori was quoted as telling Kanagawa Prefectural Police that he instructed the nurses to perform the procedure.
