Paraguayan police have detained two Germans and a Chilean suspected of killing a German man and his daughter while trying to get documents proving the authenticity of valuable violins.

Bernard von Bredow, a museum owner and instrument maker, was killed along with his 14-year-old daughter Lydia at their home in Aregua last month, and police said Mr Von Bredow’s body showed signs of torture.
