Recordings in Gibson case

US detectives investigating Mel Gibson in a possible domestic violence case received audio recordings from a court handling a child custody matter, authorities said.

Sheriff’s spokesman Steve Whitmore said CDs were turned over during a closed session in a custody case involving Gibson and his ex-girlfriend, Oksana Grigorieva.

The Russian singer reported that the actor-director hurt her during an argument in January.

The hearing was attended by several sheriff’s investigators, including detectives who look into possible child abuse.

Gibson and Grigorieva, 40, are locked in a bitter custody dispute over their eight-month-old daughter.

Meanwhile, Gibson’s estranged wife has filed a court declaration stating she and her children never experienced any abuse by the Academy Award winner. The divorce is ongoing.
