Malaysian police made a third arrest on Thursday in their hunt for the people involved in the murder of the estranged half-brother of North Korean leader Kim Jong Un.
The third person, whose nationality was not disclosed, was the friend of an Indonesian woman who was detained earlier in the day in connection with the killing of Kim Jong Nam at the airport in the Malaysian capital on Monday, police said.
"He was detained to facilitate investigations as he is the boyfriend of the second suspect," said Abu Samah Mat, the police chief in Selangor state, told Reuters. (For a graphic on North Korea's Kim family tree click: here)
