BOGOTA - A Colombian DJ popular with the stars but wanted by Interpol for alleged drug trafficking has been arrested in Italy, Colombian police said Wednesday. DJ “Fexter,” whose real name is Fernsterbein Fernando Ramirez, was arrested earlier this week in the northeastern Italian city of Udine. Police dubbed him “one of the most dangerous offenders” in San Andres, a Colombian island in the Caribbean, but he had lived in Italy since 2013 after fleeing the law.
