CONCORD, N.H. (AP) -- A Dartmouth College fraternity put on probation three years ago for expecting pledges to drink saltwater and enter a kiddie pool filled with condiments is under investigation again for hazing. The national Sigma Alpha Epsilon organization released no details, including what the supposed hazing was or when it happened, but said Monday it notified college administrators of the allegations and immediately ordered the Dartmouth chapter to suspend all activities.
