An 18-year-old youth has been arrested in The Hague following the discovery of a dead man and woman in a house in the city on Sunday.
According to RTL news, the youth is the son of the dead man, who was 62. The relationship between the dead man and the woman, 45, is unclear, the broadcaster said.
The youth was originally arrested with a 16-year-old boy, the son of the woman who was killed. The 16-year-old has since been released and is no longer considered a suspect.
