In a rant captured on video, a man berated employees and customers for speaking Spanish in a New York restaurant, describing them as undocumented and threatening to call immigration officials on them.

The incident happened Tuesday at a Fresh Kitchen in Manhattan, according to Edward Suazo, who posted a video of the encounter on Facebook

The video had been viewed 4.4 million times by early Thursday, with some identifying the man as lawyer, Aaron M. Schlossberg, who has an office near the restaurant.

In an email, Fresh Kitchen said the store is a public area for breakfast and lunch and welcomes everyone from all types of cultures.

In what appeared to be a reference to the incident, New York Mayor Bill de Blasio tweeted that the city's strength was its diversity.

According to the US Census Bureau, 49% of New Yorkers over age 5 speak a language other than English.
