The 54-year-old New Jersey woman suffered a broken leg after another client she was told to wear a mask dropped to the ground, authorities said.
Police released a surveillance video of the incident, which occurred Wednesday at about 3:19 p.m., in Hackensak Strait.
Margot Kagan of Teaneck told police she used a fax machine at the store when a woman with a mask ripped under her mouth approached a nearby machine. Kagan, who, according to police, had a liver transplant four months ago and was walking with sugar cane, told the woman to put on a mask.
“The suspect was angry and shouted at the victim, who picked up her walking stick and aimed it directly at the suspect, walking inches from the suspect̵7;s chest,” said Tomb Darrin DeWitt, a detective working for the Hackensack Police Department.
The woman then screamed at Kagan, forcibly threw her to the ground and left the store, DeWitt reported.
According to DeWitt, Kagan was taken to a hospital where she was diagnosed with a broken left tibia.
Gov. Phil Murphy said all residents in stores must wear face shields.
Police are seeking to identify the suspect.
Kagan did not respond immediately to the voicemail message and several calls to comment on Friday.
