The woman "cosmic artist" Jack Armstrong allegedly raped in 2010 was unconscious during the assault, prosecutors say.
Armstrong was arrested Friday at a home in Eagle Rock on a warrant in connection with arape that allegedly took place in Beverly Hills on March 4 or 5, 2010.
The Southern California artist got his nickname after christening his bright, multicolored paintings as “cosmic extensionalism.” His paintings can fetch six figures.
Armstrong, 56, was released from custody after posting bond, according to the Beverly Hills Police Department. He is scheduled to be arraigned Dec. 20 on one felony charge of "rape of unconscious person," according to a criminal complaint filed in Los Angeles County Superior Court.
"The arrest was the result of a lengthy, in-depth and multi-county investigation," Beverly Hills police said.
Authorities are seeking the public's assistance "out of concern that Armstrong may have victimized other women using his so-called celebrity status," police said.
