The father of a Turkish man accused of murdering two Co Down women has been arrested.
Recep Cetin's father was taken into custody on Thursday night to be questioned about the murders of Marion Graham and Kathy Dinsmore.
The two women were stabbed to death last August near Izmir.
Recep Cetin was the boyfriend of Shannon Graham, Marion Graham's 15-year-old daughter.
A judge ruled earlier this week that he will be required to have a bone marrow test to find out how old he is.
He claims he is 17, but lawyers representing the families of the two women believe he is older.
If he is over 18, he will be tried in an adult rather than juvenile court - meaning he would face a much tougher sentence if convicted.
