A beating involving lacrosse sticks and bottles left three college-aged males with non-life threatening injuries in an off-campus incident Friday morning in a North Pleasant Street apartment.

According to Amherst police, approximately 12 young men forcibly entered the apartment and struck several people. The three victims were treated at Cooley Dickinson Hospital in Northampton for injures, including contusions and lacerations. The names of the men have not been released.

Retaliation for a previous disagreement allegedly served as the motivation for the dozen assailants, according to the police investigation.

Amherst police have not pressed charges or made any arrests to date and are still trying to determine if the assailants are members of an athletic organization or University of Massachusetts students.

However, the Amherst police confirmed on Sunday that members of the UMass men’s lacrosse team are suspects in the ongoing investigation.

The University announced on Saturday that eight members of the team are suspended indefinitely for an undisclosed violation of team rules. The release said that the suspensions stemmed from an off-campus incident on Friday.

UMass men’s lacrosse sports information director Jason Yellin declined to comment on the nature of the suspensions. Coach Greg Canella also declined comment.

Among the suspended players is junior attackman Jim Connolly (North Andover, Mass.), the team’s leading scorer last season.

The remaining suspended players include redshirt sophomore Jordan Hendry (Englewood, Colo.), junior Justin Kelleher (Brewster, N.Y.), sophomore Chris Haggerty (West Nyack, N.Y.) and freshmen Chris Casey (Duxbury, Mass.), Jay Lucas (Bedford Hills, N.Y.), Ryan Marcus (South Hadley, Mass.) and Alex Whitney (North Hampton, N.H.).
