GIBSON EX EXTORTION INVESTIGATION COMPLETED, SHERIFF SAYS

Sheriff's detectives have finished their investigation into whether actor Mel Gibson was the victim of extortion and plan to present it to prosecutors next week, the Los Angeles Times reported today.

"The investigation is substantially done," sheriff's spokesman Steve Whitmore said. "We anticipate the district attorney will have it next week unless something happens that we don't anticipate."

Officials have spent months investigating claims that someone tried to extort money from Gibson, who is in a bitter custody dispute with ex-girlfriend Oksana Grigorieva.

Sheriff's investigators have spent months looking into whether Gibson struck Grigorieva and have said that case is closely tied to the extortion case.
