See Mark Zaretsky's article on the NH Register site. I'm sure there will be more news coming. Four officers arrested by the FBI this morning. Cari, Spaulding, Sgt. John Miller, and Jason Zullo. No charges available at this time.
Here is the indictment from the NH Register site:
MILLER, Et Al Indictment
If I am not mistaken, they mention a "co-conspirator-1" which can only be Gallo. From page 11 of the indictment it says co-conspirator-1 "ordered all EHPD personnel not to permit Police Commissioners on the premises of the EHPD station without his prior approval".
