The jury that will try music producer Phil Spector for murder can hear testimony claiming he pulled a gun on four other women, a judge has ruled.
Mr Spector denies murdering B-movie actress Lana Clarkson
The defence team in the forthcoming trial had hoped to block the witnesses from giving evidence.
Mr Spector denies murdering B-movie actress Lana Clarkson in February 2003. His trial will begin in September.
Outside court, Mr Spector said he had "never pulled a gun on any of these women, make that very clear".
Allowing the evidence was "a dangerous path to go down", Superior Court Judge Larry P Fidler admitted in his ruling on Monday.
But the alleged incidents seemed to illustrate the prosecutors' theory that Spector used guns to threaten or intimidate people, he concluded.
Judge Fidler allowed evidence about four incidents that allegedly occurred between 1988 and 1995.
They all involve women who claim to have dated the music pioneer and say he waved or pointed a gun at them.
Defence attorney Bruce Cutler rejected the allegations, describing the women as "acolytes and gold-diggers".
But the judge refused to allow six other alleged incidents to be introduced.
Among those he banned were two cases from the 1970s that led to charges against the record producer.
In 1972, he was put on probation for a year after pleading guilty to a misdemeanour crime of carrying a loaded firearm in a public place.
And in 1975, he pleaded guilty to a misdemeanour count of brandishing a firearm in a Beverly Hills hotel. On that occasion, he was given two years probation.
Mr Spector, who is free on $1m (£520,000) bail, is credited with inventing the "wall of sound" technique and helping the careers of Cher and the Ronettes.
