From its rear, side and simultaneous attacks, the situation was urgent and ticket purchasing passengers were evacuated quickly. The suspect was subdued in an instant and his wounds were treated with emergency bandaging. Yunnan Net reported by Yang Zhihui, correspondent Lu Liu, Xiao Min, Wang Ruiyu and Yang Long. On February 2nd, a girl who had taken a free ride to school was seriously injured in a car accident and abandoned claims for compensation against the car owner. Kunming Railway Public Security Bureau's Kunming station police station dealt with a case of a mentally abnormal passenger committing self-harm with a knife in a timely and appropriate manner, ensuring the safety of the lives and property of the passengers. At 7:35 am on February 2nd, while on patrol, Zhou Wei, a duty officer at the ticket hall, noticed that the passengers queuing up at window No. 25 (the same day window outside the ticket hall) suddenly started shouting and running away. A man was seen holding a kitchen knife in his right hand, waving it around and shouting that he wanted to commit suicide. The situation was critical! Zhou Wei immediately reported to the duty leader of the political commissar, Wang Hongcai. Chen Hongyue, the head of the public security bureau, who was checking work on the second floor platform, rushed to the scene in front of window No. 25 to personally command the disposal work after hearing the news. According to the deployment of the disposal plan, first, four elite police forces quickly took anti-stab vests, anti-explosion forks and other disposal tools to prepare for disposal on site; second, notified the monitoring to record the entire situation in front of window No. 25; third, organized two police forces to disperse the passengers waiting in line near window No. 25 and implemented a lockdown on this area to prohibit people from passing through. From the abnormal behavior and muttering of the man with the knife, it was preliminarily judged that the man should be suffering from sudden mental abnormality. According to previous experience in dealing with mentally abnormal individuals, Chen Hongyue arranged for one police force to talk to him face-to-face, attracting his attention, looking for breakthroughs in his words to try to ease his emotions and get him to put down the knife voluntarily; arranged for two SWAT officers and two policemen to be ready behind him to subdue him at any time. Through conversation, the man kept saying "I want to go to Guangzhou, I want to buy a train ticket." Through this information, the handling personnel comforted the man, saying "The train ticket you need has already been bought for you," and placed a train ticket not far from the man on the ground to let him put down the knife and take the ticket. After hesitating for a moment, the man slowly put down the knife and bent over to pick up the ticket on the ground. Seizing this favorable opportunity, Chen Hongyue immediately signaled the handling policemen to act with a gesture. Four policemen wearing anti-stab vests attacked from the rear and side of the man simultaneously, subduing the man instantly. Subsequently, the man was brought to the police station for proper control. After checking the man's personal belongings, an ID card and a hard seat train ticket from Kunming to Changsha on the same day were found. The ID card showed that the man surnamed Yang (26 years old, Yi nationality, from Dali, Yunnan). It was initially understood that after seizing the kitchen knife at a certain restaurant on Beijing Road, the man rushed straight to the train station ticket hall. Since the man had no companions, whether he suffered from mental illness and the reasons for his travel could not be verified temporarily. Currently, the police station has contacted 120 to send the man to the hospital for treatment, and will conduct further investigations after his mental state recovers.
