Mel Gibson is focus of domestic violence probe

LOS ANGELES — Mel Gibson was named Thursday as a potential suspect in a domestic violence investigation involving his ex-girlfriend, singer Oksana Grigorieva, earlier this year, sheriff’s officials said.

The disclosure came after detectives interviewed Grigorieva about the alleged attack in Malibu.

A sheriff’s spokesman said Grigorieva was the only person interviewed so far in the case. Gibson, 54, and Grigorieva, 40, have been involved in a custody dispute over their infant daughter — the subject of a confidential court case.

The official declined to disclose details of the investigation or any potential evidence. “We’re in the process of verifying, verifying, verifying,” he said.
