Sheriff's detectives are investigating a claim that Mel Gibson's ex-girlfriend Oksana Grigorieva engaged in attempted extortion against the actor-director, The Associated Press reports.
Los Angeles County Sheriff's Department spokesman Steve Whitmore declined to provide further details.
"Detectives will follow the investigation wherever it leads," Whitmore said.
Grigorieva's spokesman Stephen Jaffe denied any wrongdoing on the part of his client, a Russian singer.
"Ms. Grigorieva has repeatedly stated that there is no credible evidence whatsoever of extortion by her, and she stands steadfastly by that statement," Jaffe said.
Whitmore offered no timetable on when the case might be presented to the district attorney's office, which will decide whether to pursue charges against either Gibson or Grigorieva.
