AMHERST — As a relatively calm Blarney Blowout celebration continues throughout the town of Amherst, as of early afternoon police here reported just three arrests and the medical treatment of nearly a dozen young people for a variety of issues.

According to Jennifer Gunderson, a spokesperson for the Amherst Police Department, the arrests have been relatively minor with the most serious charge being domestic assault for an incident which happened outside the Mullins Center ahead of the concert with Ludacris, Ke$ha and Juicy J. Another student was charged with disorderly conduct for an incident near the Curry Hicks Cage early this morning and a 19-year-old male was charged for being a minor in possession of alcohol and having an open container in public.

At the Mullins Center, where police have revised the number in attendance from nearly 7.500 to around 5,000, Gunderson reports that 8 people were treated in the triage area for unspecified issues, one was taken into protective custody for alcohol intoxication and one person taken to Cooley Dickinson Hospital by the Amherst Fire Department.

But many of the students and young people attending the concert said they were just there to have a good time and wanted no part of the rowdiness which has marred past Blarney Blowout celebrations and damaged the reputation of UMass Amherst, local police departments and the town itself.

But despite the aforementioned incidents, the efforts of police from more than 14 departments to disperse any large groups of young people gathering in town has thus far proved effective in preventing a repeat of the violent 2014 Blarney Blowout clashes between police and young people.

Around North Amherst off-campus apartment complexes, where much of the trouble has been concentrated in the past, police are preventing any non-residents from entering the properties or courtyards.

"The Amherst Police Department continues to monitor groups of pedestrians that are walking throughout north Amherst," Gunderson said. "Alcohol violations are not being observed and there have been no reports of property damage."

PVTA buses at the stop on Route 63 have been busy with groups of students taking rides elsewhere after being dispersed by police.

Gunderson said there are a number of smaller parties all over the town, but none have caused any significant issues so far in the day.

The bars downtown don't open until 4 p.m. this year so as of 3 p.m., there was still ample parking and relative calm as no calls for service have come from the downtown area today, according to police.
