First responders in town were busy on Saturday, dealing with thousands of college students taking part in this year's Blarney Blowout.
Local bars started the event to allow college students to celebrate St. Patrick's Day early, as they will be away from campus during the actual holiday.
Capt. Jennifer Gundersen of the Amherst Police Department told CBS 3 that it was a very concerning day for authorities.
While Amherst police were not available for comment Sunday morning, the Associated Press reported that a total of 73 arrests were made on Saturday.
Those arrested are mostly facing charges ranging from failure to disperse, to resisting arrest and disorderly conduct.
Four police officers were injured as they worked to disperse a crowd of approximately 4,000 students from the Townhouse apartment complex, which is just north of the UMass campus.
Gundersen said the four officers were treated at the scene and were able to continue working.
To help with the crowd control, Amherst police were joined by UMass police and state police.
While things have quieted down, Gundersen said all officers on duty will continue to work through the night.
UMass put out a statement Saturday evening regarding the Blowout, stating:
"The University of Massachusetts Amherst today denounced the unruly behavior of participants in the unsanctioned "Blarney Blowout."
Ed Blaguszewski, campus spokesman, said students arrested by Amherst Police or UMass Police will have the details of their behavior reviewed by the Dean of Students under the Student Code of Conduct. Sanctions can include suspension or expulsion from the university.
UMass Police worked throughout the day with Amherst Police to manage crowds that gathered, which occurred for the most part off campus. UMass Police reported three arrests, none of them UMass students. Other arrests were made by Amherst Police.
In the days leading up to the gathering, the university reached out to students, landlords, parents, faculty and staff in a campaign to communicate the importance of students acting safely and respecting the property of others.
In addition, the university sent letters to students who had been disciplined for alcohol-related misconduct in the past year and to students who live in off-campus housing cited for noise or nuisance complaints reminding them of the possible consequences of bad behavior."
