BEVERLY HILLS, Calif. – Celebrity fashion designer Anand Jon Alexander pleaded not guilty to 13 new charges of sexual assault Tuesday after at least six more women and girls accused him of abuse.

Alexander, who has dressed starlets such as Paris Hilton, is accused of meeting women on the Internet and assaulting them when they visited about modeling opportunities between 2002 and 2007. His defense has claimed some of the women made the allegations to seek fame.

At least 18 women and girls, ranging in age from 14 to 27, have accused him of abuse.

Alexander now faces more than 40 felony and misdemeanor counts of sexual assault that include rape, sexual battery and committing a lewd act on a child, said Jane Robison, a spokeswoman for the Los Angeles County district attorney’s office.

He has pleaded not guilty to all previous charges and could face life in prison if convicted on all counts.

Alexander is free on bail after being arrested in March. Superior Court Judge Elden Fox denied a prosecution request Tuesday to increase Alexander’s bail to $2.3 million.

Alexander was arrested in March at his Beverly Hills apartment. There also are criminal investigations in New York and Massachusetts, Robison said.
