The fastest search for a fraudster in history. Over a decade ago, a client from Zhenjiang, another place, came to Shenzhen and said that they had been defrauded of 300,000 yuan in cash by someone they had only met once. The client had already reported the case to the Luohu Economic Investigation Bureau. Now, they only have a mobile phone number and occasionally turn it on. After analysis, we believed that this was not a professional fraud case. Then, through technical means, the mobile phone signal was locked and it appeared once on a certain street in Guanlan Street. Then on the same day, we went there with the client to wait and search. In fact, it usually takes about three to five days to find a person, and sometimes even ten days. We didn't have much confidence that day. We searched for most of the day. By six o 'clock in the evening, the client said we should have dinner first. We sat down at a restaurant by the roadside to order food. We could just see people walking on the street through the glass. I told the client to keep an eye out and I would order food. The waiter had just arrived when the customer suddenly got excited and pointed outside, saying, "Look, it's that person." I was also a bit surprised. What a coincidence! I told the customer to make sure, but he said it was not convenient to do so. It was an old man in his sixties. I said, "OK, because he knows you. Let's prevent him from running away. Let's follow him. You follow us." While following, you called the Luohu Economic Investigation Bureau and said, "The person has been found." Finally, we identified the whereabouts of the fraudster. After waiting, the economic investigation team also arrived. We then arrested them all together and brought them to Luohu. The client was very satisfied. This was the fastest time we had searched for someone, and it was still a pleasant surprise!
