The Force.net reports the following..
"A new character named Zam Wesell appears in several scenes with Obi-Wan Kenobi and Anakin and is female! I have reason to believe that Zam Wesell is also played by none other than Australian actress Leeanna Walsman. She is not playing Aurra Sing as was previously reported."
"They have just taken Zam Wesell out into the back alley of the nightclub on Corusant to interrogate her. As the Jedi attempt to get this important information from her, a character raises their weapon, the Kyber Dart, and fires at the unsuspecting Wesell. The toxic dart hits its target and Zam slumps to the ground. Jango Fett is satisfied that the information is protected and his mission is accomplished."
