George Clooney calls for action in South Sudan

The Hollywood star and his journalist father Nick were placed in handcuffs and driven away by secret service agents.

The actor was charged with crossing a police line.

As he was led away, Clooney admitted his arrest was deeply humiliating, reports femalefirst.co.uk. He was released after two hours and held an impromptu press conference urging US politicians to act now to put a stop to Sudan's President Omar Al Bashir's quest for oil and the atrocities he's accused of committing against his own people.

Clooney warned that the people of the newly independent South Sudan faced starvation as they hide out in caves to avoid attacks and bombing raids on their homes.
