Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Upon receiving the call, Lu Chuan took it very seriously and immediately convened an emergency meeting to deploy the arrest operation. He clearly instructed Wang Shuai to lead the investigation team to Lijia'ao Village immediately to ascertain Zhang Laibin's hiding place and closely monitor his movements to avoid alerting him. At the same time, he dispatched the special police detachment to provide support, setting up a perimeter around Lijia'ao Village and blocking all entrances and exits to prevent Zhang Laibin from escaping. In addition, he arranged for team members to go to the convenience store again to retrieve the surveillance footage and carefully compare Zhang Laibin's walking posture and clothing to confirm whether he was the suspicious man captured on camera. Simultaneously, he collected Zhang Laibin's fingerprints and DNA samples and compared them with the fingerprints and DNA of suspects collected at the scene, as well as saliva residue on cigarette butts, to further confirm his suspicion.

Upon receiving the order, Wang Shuai immediately led his team to take swift action. They first went to the home of a village official in Lijia'ao Village to obtain detailed information about Zhang Laibin, including his home address, usual activities, frequent contacts, and recent activities. According to the village official, Zhang Laibin's home is a simple mud-brick house located at the north end of Lijia'ao Village. He lives there with his elderly father, who is bedridden and unable to care for him. Zhang Laibin is rarely home, spending most of his time wandering around the village, drinking and chatting at the village store, and sometimes roaming the surrounding villages. Recently, his behavior has been rather strange; he often wears a mask, is nocturnal, and sometimes wanders the village roads in the middle of the night. He also appears emotionally unstable, occasionally losing his temper and swearing, making him unapproachable by many villagers.

In addition, village officials reported that three nights ago, around the time of Li Yongbao's death, someone saw Zhang Laibin near the dirt road at the west end of the village. At the time, he was wearing a black coat and a mask, carrying a black package, and looking hurried. He walked along the dirt road towards Lucao Gou Village. About an hour later, he hurriedly returned to the village along the dirt road, and his clothes seemed to be covered in mud. At the time, everyone thought he was going to Lucao Gou Village to steal something and didn't think much of it. Now, looking back, his whereabouts are indeed very suspicious.

After learning this information, Wang Shuai became even more certain that Zhang Laibin was the suspect in the case. He immediately led his team to Zhang Laibin's home to investigate. Zhang Laibin's house was located in a secluded corner at the north end of the village, with no other villagers around. The door was tightly closed, and the yard was overgrown with weeds, making it look very desolate. Wang Shuai signaled his team members to spread out around the house and closely monitor the movements inside. At the same time, he quietly walked to the door and listened carefully to the sounds inside. He discovered slight movements inside, suggesting that someone was inside.

To avoid alerting the suspect, Wang Shuai didn't knock on the door rashly. Instead, he arranged for two team members to quietly climb the courtyard wall and peer into the house. Once on the wall, they observed a man sitting at a table in the main room, drinking and smoking. He was wearing a black jacket and dark trousers, had short hair, and was of medium build—a perfect match to Liu Mei's description of Zhang Laibin. Furthermore, a black knife lay before him, with what appeared to be dark red stains, possibly blood. Even more suspiciously, the man was wearing black rubber-soled sneakers with a faint diamond-patterned tread pattern, closely matching the size 43 diamond-patterned rubber sole print found at the scene.

Two team members quietly climbed down the courtyard wall and reported their observations to Wang Shuai. Wang Shuai immediately decided to launch the arrest operation. As planned, he assigned his team members to guard the front and back doors and windows of the house to prevent Zhang Laibin from escaping from other places. At the same time, he called the special police detachment, informed them of Zhang Laibin's exact hiding place, and requested their immediate assistance.

A few minutes later, members of the SWAT team arrived at the scene and joined up with the investigation team led by Wang Shuai. After briefly explaining the situation and the arrest plan, Wang Shuai immediately issued the arrest order. "Action!" With Wang Shuai's command, the SWAT team members and the investigation team immediately launched the arrest operation. Two SWAT officers kicked open the door and rushed into the house, shouting, "Police! Don't move! Drop your weapons!"

Upon hearing the shouts, Zhang Laibin, inside the house, panicked and jumped to his feet, trying to grab a knife from the table to resist arrest. However, he was too slow; two SWAT officers rushed forward, pinned him to the ground, and firmly restrained his hands and feet, rendering him immobile. Zhang Laibin struggled desperately, shouting, "What are you doing? Let me go! I haven't broken the law! What right do you have to arrest me?"

Wang Shuai entered the house, his eyes fixed on Zhang Laibin, and said in a calm tone, "Zhang Laibin, we are police officers from the Municipal Criminal Investigation Detachment. We suspect you of intentional homicide. We are now arresting you in accordance with the law. Please cooperate with our work and do not resist. Otherwise, we will take coercive measures in accordance with the law!"

Upon hearing the words "intentional homicide," Zhang Laibin's struggles weakened instantly. His face went from panic to deathly pale, and his eyes were filled with terror. Yet, he remained defiant, shouting, "I didn't kill anyone! I didn't kill Li Yongbao! You're framing me! You've got it wrong!"

Wang Shuai ignored his excuses and signaled to his team members to search Zhang Laibin. The team immediately conducted a thorough search of the house. Next to the table, they found the black knife. A preliminary examination confirmed the dark red stains on the knife were blood, which initially matched the blood of the deceased, Li Yongbao. In a corner of the house, they found a black jacket with a small amount of dirt and dark red stains. Comparison showed the jacket's material and style were identical to the black jacket worn by the suspicious man in the convenience store's surveillance footage. In the wardrobe, they found a pair of black diamond-patterned rubber-soled sneakers, size 43, which perfectly matched the suspect's shoe print found at the scene. Additionally, in a drawer, they found a silver-white metal button, approximately 1.5 centimeters in diameter, with a patterned surface, which was identical in style and material to the metal button recovered from the scene, presumed to have been removed from the suspect's clothing.
