LA Police Want to Speak to Mel Gibson a Third TimeMel Gibson has been seeing a lot of the LA County Sheriff's Department lately. Investigators are looking to speak with the actor for a third time in connection to extortion claims against Oksana Grigorieva, TMZ reports.

Law enforcement sources tell TMZ the continuing series of interviews strongly hints at the department taking the extortion case very seriously, though the investigation won't wrap for at least several weeks.

In July, Gibson, 54, initially seemed the sole bad guy in a series of leaked tapes of him screaming at ex-girlfriend Oksana, the mother of his baby daughter. TMZ quickly advanced the story with sources boasting "hard proof" that Grigorieva used audio rants to attempt to extort him of more than $10 million. In return, she allegedly would have kept the tapes under wraps.
