It happened around 7 a.m., when police sources tell CBS2 the victim was attempting to break up a fight between two men.

“Other people tried to break it up and she went and grabbed somebody and tried to pull them away,” the victim’s uncle, George Samuels, said. “Then all of sudden, next minute she got hit in the back of the head with a pole.”

The victim suffered lacerations. Police say she was taken to Bellevue Hospital, where she received stitches and was released. Samuels says he told her next time, don’t get involved.

“She helps other people, and I told her about that,” he said. “I said nowadays, you can’t do that.”
