She owed 100,000 yuan and had a dispute with her creditor during negotiations. Her girlfriend called the police and found that her boyfriend was in possession of drugs and was wanted.

The police found amphetamines and etomidate in the rooms of Zhong Nan's couple and Zhang Nan respectively. They also found that Zhong Nan was a wanted fugitive on fraud and drug charges.

A 39-year-old man surnamed Zhong owed a debt of 100,000 yuan to a 33-year-old man surnamed Zhang. Since both of them lived in a building on Section 2, Zhongshan Road, Zhonghe District, New Taipei City, Zhong Nan and his girlfriend Chen Nv met at Zhang Nv's residence to discuss the repayment method this morning (6th). During the process, both parties became excited. Chen Nv was worried about her boyfriend's safety and left first. Calling the police, officers from the Zhongyuan Police Station of the Zhonghe Branch under their jurisdiction were notified and rushed to conduct an investigation. They found amphetamines, etomidate and other drugs in Zhang Nan's room and Zhong Nan's couple's room respectively. They also found that Zhong Nan was a wanted criminal on suspicion of fraud and drug crimes. The police arrested Zhang Nan and Zhong Nan on the spot and sent them to justice according to law.

Police investigation revealed that Zhang Nan met Zhong Nan at his residence at around 9 a.m. today to discuss specific repayment methods. During the negotiation, the two sides argued fiercely and the tone was quite emotional. Because Chen was worried that her boyfriend's life would be in danger if he stayed at the scene, she left first and reported to the police that there was a dispute at the scene.

After receiving the report, the Zhongyuan Police Station assigned police officers to rush to the scene. When the police arrived at the scene, they found that both parties were no longer where they were. The police immediately launched a floor-by-floor investigation. First, they found Mr. Zhang who had stayed at the scene in the lobby of the building. Then they found Ms. Chen who had left first in the basement. Finally, they found Mr. Zhong who had stayed in the room on the 8th floor of the building.

The police took the three people back to their respective rental apartments for investigation and obtained consent to conduct the search. First, they found the drug amphetamine and the emerging drug etomidate in Zhang Nan's rental apartment on the 9th floor. Then they went to the suite where Chen and Zhong Nan lived together on the 8th floor to search, and also found the drug etomidate in the room. When the police checked the identities of the three people through the police information system, they were shocked to find that Zhong Nan had already been wanted by the court on suspicion of fraud and drug cases.

Zhang Nan confessed to the police that he was in possession of the drugs found in the room; as for the etomidate seized in the room of Chen Nv and Zhong Nan, since the two lived in the same room, the police took them back together to further clarify the actual ownership of the drugs. After the police interrogation, Zhang Nan was transferred to the New Taipei District Prosecutor's Office for investigation on drug charges; Zhong Nan's wanted department was transferred to the issuing district prosecutor's office and court according to the relevant wanted cases.
