SEOUL, South Korea (AP) – Police on Friday investigated the motives of the anti-U.S. activist they say slashed the U.S. ambassador to South Korea as questions turned to whether security was neglected.

The attack Thursday on Mark Lippert, which prompted rival North Korea to gloat about “knife slashes of justice,” left deep gashes and damaged tendons and nerves. But it also raised safety worries in a city with a reputation as a relatively low-risk diplomatic posting, despite regular threats of war from Pyongyang.

While an extreme example, the attack is the latest act of political violence in a deeply divided country where some protesters portray their causes as matters of life and death.

Lippert, 42, was recovering well but complaining of pain in the wound on his left wrist and a finger where doctors repaired nerve damage, Severance Hospital official Yoon Do-Heum said in a televised briefing. Doctors will remove the 80 stiches on Lippert’s face on Monday or Tuesday and expect him to be out of the hospital by Tuesday or Wednesday. Hospital officials say he may experience sensory problems in his left hand for several months.

Police, meanwhile, searched the offices of the suspect, Kim Ki-jong, 55, for documents and computer files as they investigated how the attack was planned and whether others were involved. Police plan to soon request a warrant for Kim’s formal arrest, and potential charges include attempted murder, assaulting a foreign envoy, obstruction and violating a controversial South Korean law that bars praise or assistance of North Korea, Jongno district police chief Yun Myung-sung told reporters.
