4 North Korean suspects sought

Investigators are looking for four North Korean men who flew out of Malaysia the same day Kim Jong Nam, the North Korean ruler’s outcast half brother, apparently was poisoned at an airport in Kuala Lumpur, Malaysian police said Sunday.

Since Kim’s death last week, authorities have been trying to piece together details of what appeared to be an assassination. Malaysian police have so far arrested four people carrying IDs from North Korea, Malaysia, Indonesia and Vietnam.

Malaysia’s deputy national police chief, Noor Rashid Ibrahim, said four other North Korean suspects were on the run.
