ALHAMBRA, Calif. (AP) — Phil Spector, who is awaiting trial on a murder charge, was arrested Friday after getting into a scuffle with his chauffeur at the music producer's mansion.

Both men were arrested for investigation of misdemeanor battery. Police arrived at the home around 10:15 a.m. to find them attempting to place each other under citizen's arrest, Police Lt. Elliot Kase said.

"They had an issue over their business relationship," Kase said. "We're not exactly sure what the issue was, but they didn't seem to come to agreement. It was mutual combat, so they chose to arrest each other."

Spector was charged last year with murdering actress Lana Clarkson, who was found shot in his mansion on Feb. 2, 2003. He has denied the murder allegation and has suggested the woman killed herself. The case has yet to go to trial.
