A man accused of having sex with a female acquaintance without telling her he was infected with AIDS once boasted he would take all the women he could with him, a prosecutor said.

William Lucas Barker, who was charged Friday with assault with a deadly weapon, set out to "ritually infect future sex partners out of spite," said Robert Chambers, an Alameda County assistant district attorney.The 25-year-old Oakland man has been ordered held without bail.

Barker was released from prison in January after serving a term for parole violation. He was diagnosed in prison as having the AIDS virus. It was not immediately known how or when he contracted it, police said.

Barker was arrested Tuesday in a motel room after having sex at least four times over several days with a 22-year-old woman who was a casual acquaintance, police said.

Barker did not tell the woman he was infected with AIDS, said police Sgt. Sue Hoffman. When officers told the woman, she became hysterical and tried to attack him, Hoffman said.

A parole official received information that Barker had boasted that once he was out of prison he would "take all the women I can with me before I die," a police officer told The Tribune in Oakland.

The newspaper did not identify the officer by name.

Barker apparently has shown no symptoms of AIDS, authorities said. It was not immediately known if the woman, now under a doctor's care, has contracted the virus.
