On the 19th of this month, a child at an elementary school in Tokyo's Suginami Ward tried to drink tea from a water bottle he had brought home after school. When the principal examined it, they found that it was not tea but a yellowish liquid with a chlorine-like odor.
Although the child drank a small amount, there were no health problems, and the school is taking measures such as consulting with the police. The police plan to conduct further investigation by interviewing parents and schools about the circumstances surrounding the incident.
