A man trying to intervene in a domestic assault at a Hamilton Township bus stop suffered critical injuries when the suspect punched him in the head, police said.
Several people pulled off busy Route 40 near Cantillon Boulevard Thursday morning after seeing 24-year-old Calvin Wiggins of Sicklerville, New Jersey beating his girlfriend, police said.
The passersby tried to intervene, but witness George Sluker, who lives across the street at a condo complex, said Wiggins threatened them.
"The fella doing the beating was yelling at the people trying to stop him that he was going to shoot them," Sluker said.
Sluker and another witness said that's when he turned and punched one of the men.
"This guy just cold clocked him," Sluker said.
The man dropped to the ground and hit his head with such force people standing across the road could hear the impact.

A driver distracted by the incident crashed into a sign, springing a fuel leak that forced the road to be shut down for cleanup.
