SEOUL - South Korean police on Jan 8 arrested a second man linked to an attack last week on opposition Democratic Party leader Lee Jae-myung, the Yonhap news agency reported.

Lee was stabbed in the neck by a 67-year-old man who lunged at him with a knife after asking for his autograph during a visit to the southern port city of Busan.

The man, who was only identified by his surname Kim, was arrested.

The police arrested another man in his 70s in the central city of Asan, where Kim lives.

The second man was detained over charges of helping mail a letter written by Kim about his motive behind the attack to the police, Yonhap said.

Calls to the Busan police went unanswered.

Lee was recovering at a hospital in Seoul after undergoing surgery to repair a major blood vessel. REUTERS
