(LEAD) S. Korea unveils tougher measures to curb illegal Chinese fishing near NLL

A Chinese man was formally arrested in South Korea on Thursday for the murder and mutilation of a 25-year-old Chinese graduate student, according to Yonhap news agency. The arrest warrant was issued by the Daegu District Court, citing concerns that the suspect, identified as Jeong, may flee. The victim's lifeless body was discovered at the suspect's residence in Gyeongsan, a southeastern city, on Tuesday, five days after she had gone missing.

Jeong was apprehended by the police on the same day as the discovery. During questioning, Jeong confessed to the murder and revealed that he had scattered parts of the victim's mutilated body in Gyeongsan and in northwestern Gyeonggi Province, approximately 240 kilometers away, the Gyeongsan Police Station reported. In response to the brutal nature of the crime, police are considering conducting a psychopathy evaluation on Jeong.
