Validation of arrest and ban on staying in Rome for Ludwig Koons, son of Jeff Koons and Ilona Staller, former congresswoman and known in the adult film world as Cicciolina. The security measure was ordered by the Capital Court in summary proceedings held yesterday. The 30-year-old was arrested also yesterday after Carabinieri found a teaser in the house where he lives. The search had been triggered after a complaint by Staller, who told law enforcement officials that she had been threatened by her son with the weapon in order to get money. "It is true that we have squabbles with my mother, but I never threatened her," Ludwig Koon defended himself, adding that he did not know that "the taser was illegal".
