Colorado State University students had not even attended their first classes when they found out about a back to school pool party on Facebook.
The party started at 1pm and everything seemed to be going just fine. Within an hour or two a little more than 4,000 people bombarded the small pool area.
By 3pm police and EMT's were on the scene to treat people for alcohol overdoses. When it was all said and done, four people were arrested, including two of the football teams star players. 10 more people were sent to the hospital, and hundreds peed in the pool. Check out the insanity below.
