LONDON • No, it is not the plot of an upcoming Angelina Jolie thriller.

Documents from the Hague-based International Criminal Court that were leaked to a French investigative website showed that the actress once volunteered to take part in a bid to nab Ugandan warlord Joseph Kony in 2012.

According to The Sunday Times, she wanted to "invite Kony to dinner and then arrest him", read an e-mail message sent by former International Criminal Court chief prosecutor Luis Moreno Ocampo.

"She loves to arrest Kony. She is ready. Probably Brad (Pitt, her former husband) will go also."

The warlord was indicted for war crimes in 2005 by the International Criminal Court.

Although the plan involving Jolie never took off, the revelation may not be as incredible as it may appear to many people.

The 42-year-old actress has done goodwill ambassadorial work for the United Nations Refugee Agency.

In 2009, she was in the Hague to witness Mr Ocampo prosecute Congolese warlord Thomas Lubanga who, among other charges, was accused of using child soldiers.

Jolie's movie First They Killed My Father - based on Cambodia's genocide - has been submitted as the country's entry for next year's Best Foreign Language Oscar race.
