An undated police handout shows Norwegian Anne-Elisabeth Falkevik Hagen, who is the wife of real estate investor Tom Hagen, and has been kidnapped according to police in Norway. Police refused to confirm the exact amount, but said they have advised Hagen's family not to comply.
The kidnappers have threatened to use violence against her if her family does not meet their demands, Norway's newspaper of reference Aftenposten said, adding that there had been limited contact with the suspects.
Brøske noted police have received no proof that Hagen is alive, "but we haven't received any indication that she isn't alive either".
Sources have now indicated that a written message was found in the Hagen house, which demanded a $10 million ransom be paid entirely with the privacy-focused cryptocurrency Monero.
