Malaysian police today detained a third suspect in connection with the murder of Kim Jong-nam, the half-brother of North Korean leader Kim Jong-un, an officer said.

"He was detained to facilitate investigations as he is the boyfriend of the second suspect," Selangor state police chief Abu Samah Mat told Reuters.

He was referring to a woman arrested earlier in the day. She was holding an Indonesian passport.

Yesterday, a female suspect with Vietnamese travel documents was arrested.
