I don't know what kind of investigation went on, and this is most definitely a crappy thing to do that can only cause family resentment in the short term (and maybe the long term), but it is possible you might bluff your sister with, "If you don't let me see my nephew and niece at least occasionally, I will call child services on you again." I'd use that as a last resort, if at all.
If the kid has any other caregivers, especially daycare or kindergarten, then definitely alert them that you saw that and ask them to be extra-vigilant.
