Three people were arrested for allegedly assaulting a New York City restaurant hostess on Thursday after she asked a group of diners visiting from Texas to show proof they had been vaccinated before seating them.

Cellphone footage obtained by NBC New York shows a brawl involving several people outside Carmine’s Italian restaurant on the Upper West Side. Staff and bystanders intervened to break up the melee after it broke out around 5 p.m. ET, the station added.

The hostess, who has not been identified, was repeatedly punched and her necklace broken, police said.

One unspecified patient was taken to the Mount Sinai Hospital, the New York City Fire Department said, without stating their condition.
