The police station chief who was the umbrella for the black gang was sentenced to 12 years in the first trial of the apartment case. Investigation found that the male infant was thrown down from an apartment located on the 10th floor by his father, and it was also his father who made the emergency call. The baby's father told the police: "I tried to kill my son, I wanted to strangle him with my hands, then threw him out of the bedroom window." The baby's family members told the police that the 37-year-old suspect looked like he had been "unhappy about his work recently." The police arrested the baby's father on the same day, preparing to file charges against him, possibly for murder. According to Xinhua News Agency, Japanese media reported that Tokyo police received a phone report on the 15th, saying that a baby was hanging on the tree crown crying. The police rushed to the scene and saved the baby. The police said that after a preliminary check, the baby was not seriously injured, only having facial scratches caused by branches.
