Saturday's nice weather prompted more shoppers to go to the mall, after a cold winter with lots of snow that kept people inside on weekends.
Police were called at 4:43 p.m. to Aisle 18 in the parking lot, by Nordstrom. A driver had been waiting to pull into a spot when another driver pulled in first.
The 42-year-old driver, from Philadelphia, told authorities she did not know that the other driver had been waiting for the spot until the two women in the car got out and confronted her, police said.
The verbal dispute escalated into a physical altercation, with one woman biting down on the finger of the victim so hard that it was nearly severed, police said.
Humes said it was unclear which driver got to the parking space first. The incident turned into an aggravated assault, he said.
The victim was treated at Cooper University Hospital. Authorities said the finger, which was hanging by just a thin piece of skin, was reattached.
Police believe the attack was carried out by a woman in her mid-30s. She was described as a black female, heavyset, with "bushy" hair, who authorities believe was driving a dark-colored older model Audi sedan.
On Tuesday, police also released photos of the other woman with the alleged attacker, and two male teenagers they believe were with the driver.
Anyone who witnessed the dispute or knows the identity of those in the images is asked to call the Cherry Hill Police Department at 856-488-7828.
