Grand Jury Indicts Nick Prugo

TMZ has learned Nick Prugo has been indicted by the L.A. County Grand Jury -- in connection with his alleged role in the Burglar Bunch crime spree.

It's unclear why the D.A. took the case to the Grand Jury, since prosecutors have already charged Prugo with numerous felonies, in connection with the burglaries of Audrina Patridge, Lindsay Lohan, Paris Hilton, Rachel Bilson, Orlando Bloom, Brian Austin Green, and Megan Fox.

An L.A. County Superior Court judge will formally receive the Grand Jury indictment this morning. The judge will then set bail.

As for why the D.A. went to the Grand Jury, there are a variety of reasons, not the least of which is that there will be no preliminary hearing. At a prelim, the celeb victims might be forced to testify, and this is a way to avoid that spectacle.

We're also told the D.A. goes to the Grand Jury when the scope of the case and the charges expand.

UPDATE: Another Burglar Bunch Defendant, Courtney Ames, just showed up in court. We do not know if the Grand Jury also indicted her.

UPDATE 12:15 PM PT: The whole BB crew -- Nick Prugo, Rachel Lee, Diana Tamayo, Courtney Ames, and Roy Lopez Jr. -- all pled not guilty today.
