Italian bodybuilder, boxer and actor Franco Columbu, one of Arnold Schwarzenegger's closest friends, has died in his native Sardinia. He was 78.

Columbu died at John Paul II hospital in the city of Olbia after he became ill while swimming in the sea, the hospital said. He lived in Los Angeles for years but was vacationing in Sardinia.

Schwarzenegger, a bodybuilder before he turned to acting, posted a warm farewell on Twitter about the man he called "my best friend." He often referred to Columbu as the strongest man he ever knew.
