Another woman has stepped forward to accuse San Diego Mayor Bob Filner of sexual harassment, and she was accompanied at a press conference this afternoon by civil rights lawyer Gloria Allred. While Allred confirmed that she’s not filing suit against Filner on behalf of vocational nurse Michelle Tyler (yet), she urged the city to conduct an investigation — and to hang a warning sign outside the mayor’s office in the meantime.

Really? It’s a shame the skull-and-crossbones sign was so clownish, because the charges themselves were anything but. Tyler claimed she was harassed when she met with Filner on behalf a Marine injured in Iraq, who also attended today’s press conference.

Allred says she’s talked to more women who have stories to tell. At the moment, Filner is facing only one sexual harassment suit.
