Domenico D'Ippolito, 24, of Cortlandt Manor; and Peter Andolina, 21, and Robert Casey, 22, both of Peekskill, allegedly ambushed four people camping in Sylvan Glen Park on the night of April 16, police said.
The suspects allegedly used baseball bats on the victims, causing three of the victims to be hospitalized due to their injuries, police said.
DNA evidence allowed authorities to identify the four men as suspects and subsequently arrested them on Tuesday, police said.
All four men were remanded to Westchester County Jail and are scheduled to appear in court on Thursday night, police said.
