Police were checking area hospitals to see if Danny Vlado had gone to their emergency rooms after the 4:30 p.m incident, Police Chief Michael Foligno said.
The gang of four knocked Vlado to the ground, then kicked and punched him outside their home, above a mini-shopping strip on the highway's eastbound side (see photo), Foligno said.
Vlado stabbed two of them -- one in the head, the other in the hand, the chief said.
He then fled, hitting two cars with his vehicle, which witnesses described as a greenish-blue Chrysler Pacifica with front-end damage.
Neither injury was considered life-threatening, Foligno said.
Charged with assault and rioting were Matthew Eley, 20, Jimmy Eley, 21, and Steve Thompson, 29. A 16-year-old boy was served with a delinquency complaint alleging the same offenses.
All were released pending court hearings.
Meanwhile, investigators were trying to determine the motive for the attack on Vlado, Foligno said.
