Federal law enforcement officers were compelled to leave a Mexican restaurant in St. Paul, Minnesota, on Sunday after patrons began hurling expletives at them, insisting they vacate the premises.

Video footage captured the federal agents making their way through Cancun Mexican Grill & Cantina while incensed customers shouted insults, trailed them, and documented the incident with their phones.

“What the heck is wrong with you all?” one man exclaimed.

“No wonder you have to wear a mask, you absolute pieces of garbage,” another individual was heard saying.

Customers could also be heard in the video asking if the agents had a warrant to be at the restaurant, noting the business asked them to leave.

Federal immigration agents are allowed to enter public areas of businesses without permission, but cannot access private areas like offices, kitchens, storage rooms or employee-only hallways without authorization or a warrant.

“Take off your mask,” a woman yelled. “Take off your mask!”

As the agents walked out of the business, others raised their middle fingers and shouted, “get the f— out of here, you fat little b—-,” “Coward m———–,” “Unamerican pieces of s—,” and “f—— Nazi pieces of s—.”

The incident came as tensions flared nationwide in response to the fatal shooting of 37-year-old Renee Nicole Good by an ICE agent in Minneapolis on Jan. 7.

Department of Homeland Security (DHS) officials allege Good hit an ICE agent with her car while blocking an immigration enforcement operation, causing him to suffer internal bleeding to his torso.

Democrats criticized the agent’s action immediately after the shooting, calling her death a “murder.”

DHS did not immediately respond to Fox News Digital’s request for comment.
