Police officials to investigate Mel Gibson again

One source close to the investigation said that the second round of questions shows how seriously the Department is taking the investigation of Oksana Grigorieva and Mel’s claim that she tried extorting him for millions in connection with the incendiary tapes.

As TMZ found out, Mel has cooperated with investigators and will continue to cooperate by sitting for another interview.

A law enforcement sources say that investigators informed Mel’s lawyer they won’t ask questions about the domestic violence case.

The Sheriff’s Department turned the domestic violence case over to the D.A. Wednesday but the extortion investigation continues.
