Amherst police made a second arrest in connection to the off-campus brawl that left three people hospitalized last week, charging Ryan Marcus, 18, of 131 Mosier St. South Hadley, with two felonies earlier this afternoon.

Marcus – the second member of the University of Massachusetts lacrosse team police have taken into custody in the past two days – has been charged with breaking and entering at nighttime and assault and battery resulting in serious bodily injury.

According to police reports, Marcus’ arrest came after a week-long investigation of the incident at 304 North Pleasant St.

Marcus, a freshman, and seven other members of the men’s lacrosse team were suspended indefinitely last week for violating team rules during an off-campus incident.

Police placed teammate Christian Haggerty under arrest yesterday, charging the sophomore UMass student with one count breaking and entering and two counts assault and battery.

Marcus – arrested in the Thoreau dormitory at 3:30 p.m. this afternoon – is being held in lieu of a $1,000 bail.

He is expected to be arraigned in the Eastern Hampshire District Court on Feb. 11.
