Authorities say University of Dayton student neighborhoods toned down their St. Patrick's Day partying this year.
School officials said in a statement Monday night that students celebrated responsibly overall. Three people were arrested Monday afternoon in a gathering after classes ended, and police said there were at least 10 citations for violations of city open container laws.
It wasn't known immediately whether the people arrested were UD students.
The Dayton Daily News reports that university officials last week sent a letter to students urging them to keep celebrations in line. Last year's parties triggered bottle-throwing melees, damaged vehicles, and the arrests of seven people who weren't UD students.
The school this year prohibited outside guests in dorm rooms over the weekend.
