A woman using a copy machine at a New Jersey Staples store last week ended up with a broken leg after she asked a fellow customer to put on her face mask. The alleged victim, 54-year-old Margot Kagan, says 25-year-old Terri Thomas came up to the machine next to hers with her mask pulled down below her mouth. When Kagan asked her to pull it back up, police say Thomas angrily shouted at Kagan, then threw her to the floor. Thomas was arrested yesterday and is being charged with second-degree aggravated assault. Kagan, who walks with a cane and can be seen using it to fend Thomas off in surveillance video of the incident, had a liver transplant four months ago.
