Frustrated Malaysian police release North Korean suspect

Malaysia issued an arrest warrant for a North Korean airline employee Friday over the assassination of the half-brother of Pyongyang’s leader, after frustrated police had to release their only other suspect from the isolated nation.
Ri Jong-Chol is among eight North Koreans suspected of involvement in the dramatic killing of Kim Jong-Nam, the half-brother of the reclusive nation’s leader, who was poisoned with a banned nerve agent at Kuala Lumpur International Airport.
