Spanish police say they have arrested the leader and eight other members of an international ring allegedly involved in extortion and illegal arms sales.

Spanish police say a raid on an upscale house on the Mediterranean island of Ibiza led to the arrest of nine suspects, including "a Polish multimillionaire and former soldier" who allegedly led the ring. The police say the ring used a network of companies in Germany, Belgium, France and Britain to "commit fraud and carry out the suspected sale of arms."

The ringleader is alleged by Spanish police to have been involved in the sale of over 200,000 AK-47 assault rifles, missile launchers and tanks to South Sudan during the armed conflict in the African country.
