More must be known about the incident. Was it actually a "crime" (i.e.: a statutory criminal offense), or was it simply a violation of institutional (i.e.: correction department) "rules?" If an actual crime then the same statute of liability applies as would if you were not already incarcerated.
You must be charged with something in order to be arraigned, and you must generally be presented to court to be arraigned within 24 hours of arrest.

In order for a person to be charged with a serious federal crime, a federal grand jury must be convened and an indictment issued. The Grand Jury and right to a trial by jury were put in place to make sure citizens weren't victimized by overly eager police officers and prosecutors.
