The woman who taped Donald Sterling has been accused by the NBA of extorting the Clippers owner ... and she also taped hours of conversations which could be a crime if she didn't tell him in advance -- so it's baffling that V. Stiviano just showed up at the L.A. County D.A.'s office.
Sources connected with Stiviano tell us ... she didn't go there over a case, but to "visit friends." We're told she worked at the D.A.'s office as an intern a few years back and she just wanted to see some old pals ... yes, it's bizarre.
And if she's just visiting ... why is she carrying a briefcase?
For the record ... the Clippers statement accusing her of extortion is incorrect. They are referring to a lawsuit filed by Sterling's wife Shelly, claiming she connived more than $1.8 million from Donald.
