MUSIC legend Phil Spector has been assigned to a “sensitive needs facility” in California’s largest state prison to serve his sentence for murdering an actress.

Authorities in the US are investigating an internet posting that appeared to threaten the judge in music producer Phil Spector’s murder trial.

Phil Spector's young wife has been told she faces a contempt of court charge if reports she's planning to prematurely speak out about her husband's murder trial are true.

Phil Spector's lawyers have asked a judge to tell US jurors they must find the record producer either guilty or not guilty of murder with no option to find lesser offences such as voluntary or involuntary manslaughter in the death of actress Lana Clarkson.
