MISHIMA: Fifteen people were injured in a stabbing attack in a rubber factory in central Japan on Friday during which an unspecified liquid was also sprayed, emergency officials said. “All fifteen people were sent to hospital,” a firefighting department official in the city of Mishima, southwest of Tokyo, told AFP . The official, declining to be named, said that of the 15 injuries, eight were the result of stabbing and seven due to the liquid. Some local media outlets, quoting unnamed sources, said the liquid appeared to be bleach. Five of the victims were classified as “requiring emergency care” by emergency workers at the scene, but all have remained conscious, the official said. Tomoharu Sugiyama, another official from the firefighting department, told AFP a call was initially received at about 4:30 pm (0730 GMT) from a rubber factory saying “people were stabbed by someone” and that a “spray-like liquid” had been used. Japanese media, including public broadcaster NHK, reported that police had arrested a man on suspicion of attempted murder.
