The son of Hollywood director and actor Rob Reiner is being held on suspicion of the murder of his parents.
Police say 32-year-old Nick Reiner's been booked for murder after Rob Reiner and his wife Michele were found dead in their Los Angeles home.
They say he's a suspect in the case and is being held on a US$4 million bail.
US Correspondent Richard Arnold told Heather du Plessis-Allan that Reiner and his wife had apparently taken their son to a holiday party, where he had apparently been disruptive, the day before their bodies were found.
He says it allegedly led to a shouting match between the father and son.
