Anyone who catches and punishes Lucius Malfoy will find a nice juicy bonus in their next pay check. An reward of 10,000 credits will go to anyone and everyone who finds him and makes him feel as much pain as they can possibly dole out.
You can use physical attacks, magic... anything you can think of to make him feel the pain. Just don't kill him. I do want to have my turn with him.
Have fun with it.
For added incentive, to know you're not attacking an innocent man, he attacked a sweet young woman. Elena Gilbert. A young woman that would not harm a fly. Gutless, I know. I thought so too. Which is why there's such a high bounty on his head.
Added: Anyone who makes him scream, or squeal like a piggy, will earn a cool million.
