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, 64, was taken into custody and later released after a June 14 court date was set. The driver, Tobie Wheeler, remained in custody. Both men claimed to have suffered minor injuries, Kase said.

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.

According to authorities, Wheeler, 46, had worked for Spector for three months and had no connection to the murder case. A figure in the case is another chauffeur who was on Spector’s property at the time, officials said.

Calls to Spector’s lawyer Leslie Abramson were not immediately returned Friday.

Famous for his “Wall of Sound” recording technique, Spector changed the way pop records were produced while bringing fame to groups like the Ronettes and the Crystals.
