SACRAMENTO (AP) — Prosecutors will not file criminal charges after investigating an alleged attack on the wife of the California treasurer by an ex-boyfriend, the state attorney general’s office said Friday.

“The Department of Justice has thoroughly reviewed the matter referred to us by the Alameda County District Attorney’s office regarding the Feb. 3 incident at a Newark hotel involving Nadia Lockyer,” Shum Preston, an attorney general’s office spokesman, said in an email. “After reviewing the evidence, the department has determined that it will not file charges.”

The odd and very public string of incidents began at a Newark hotel room in February, after the 40-year-old Lockyer claimed she was assaulted by her ex-boyfriend, Steve Chikhani.

Lockyer, the wife of state Treasurer Bill Lockyer, has said she met and began an affair with Chikhani at a rehab facility in 2010, within a few weeks of her election to the Alameda County Board of Supervisors.

The DOJ’s Preston declined to comment about whether Nadia Lockyer will be investigated further for the allegations she made about Chikhani, and whether false statements were made to police.

Lockyer resigned from the board earlier this month, saying she wanted to focus on raising her 8-year-old son, Diego.

Chikhani’s attorney, Adrienne Dell, applauded the attorney general’s decision.

“We’re grateful that the attorney general’s office investigated and came to the right decision,” she said.

After Lockyer claimed Chikhani attacked her, the San Jose Mercury News published photographs of bruises on her forehead and neck. Dell would not comment on the photographs.

More recently, Lockyer sent an email to a newspaper reporter accusing her husband, the state’s former attorney general, of supplying her with drugs. Bill Lockyer denied those charges.

The email also said: “I can’t bear this any longer. Goodbye to everyone.” That prompted the paper to notify police.

Bill Lockyer’s spokesman could not immediately comment on the decision, and Nadia Lockyer could not be reached for comment.
