News release from the UND Athletic Department here and commentary from the United States of Hockey Website here.

No details have surfaced on the “team party” the led to the UND Athletic Department investigation.  However, the four captains originally suspended, including Kristo, were 21 years of age and underage drinking was reported.  The second set of suspensions seems to indicate something more serious, perhaps “rookie hazing” which the school frowns upon.
