Chris Hansen was revealed on Friday as the mystery donor behind the petition campaign seeking to derail the Kings' proposed new downtown arena by donating $80,000 to a group gathering signatures in Sacramento, according to a source.

Hansen is a Seattle investor who tried to buy the Kings this year.

Initial suspicion for the anti-arena campaign fell on the Maloof family, former owners of the Kings, because the family has long been represented by the law firm that wired the money, Loeb & Loeb.

The Maloofs sold the Kings to a group led by technology executive Vivek Ranadive for $535 million.
