The 42-year-old white officer was bleeding form his head and face when his colleagues were flagged down near Grove Street and Newark Avenue around 3:30 a.m. Sunday, city spokeswoman Kimberly Wallace-Scalcione said.
The officer was assaulted by a group of 10 males, who were also shouting racially motivated insults at the victim, she said.
The unnamed victim identified himself as an off-duty police officer multiple times throughout the assault before losing consciousness, Wallace-Scalcione said.
He was transported to a local hospital with severe head trauma, where he was treated and released.
