NEW YORK (AP) – A chauffeur for Yoko Ono has been arrested for trying to extort $2 million from her and threatening to kill her, police said.

Koral Karson was arrested Wednesday in Amityville after Ono reported the plot, New York Police Department spokesman Paul Browne said. Charges against him were pending.

The security staff for the widow of John Lennon told detectives in Manhattan that Karson, 50, warned Ono last week that he had secretly photographed her and made audiotapes of her in private moments and warned he would make the material public if she didn’t pay him. It was unclear if the material actually exists.

Ono also alleged that Karson threatened to kill her, Browne said.

A telephone call and an e-mail left with Ono spokesman Eliot Mintz were not immediately returned Wednesday.

Police didn’t immediately release a home address for Karson.
