SYDNEY - Australian authorities have arrested and charged a teenage foreign national for allegedly facilitating contract killings in Europe.

The Australian Federal Police (AFP) said the 15-year-old was arrested on Wednesday after officers executed a search warrant in western Sydney.

In a joint statement with Danish Police and the Swedish Police Authority, the AFP said the teenager is accused of using an encrypted application to facilitate plans for contract killings in Denmark and Sweden on behalf of a transnational crime syndicate.

The AFP said it commenced an investigation earlier in April after receiving information from Danish Police about a foreign national living in Australia allegedly linked to attempts to organize crimes-as-a-service contract killings in Europe.
