From Fox News:
Police in Minnesota began arresting anti-ICE agitators outside a hotel Monday after authorities said the demonstration escalated and was “no longer considered peaceful,” prompting officers to declare an unlawful assembly.
The demonstrators were outside the SpringHill Suites by Marriott in Maple Grove, Minnesota, where they believed U.S. Border Patrol Commander Gregory Bovino was staying.
President Donald Trump announced Bovino and many of his agents would be leaving Minneapolis as part of a reshuffling of leadership in carrying out his immigration crackdown amid bipartisan scrutiny over the immigration enforcement operation in Minneapolis that intensified after agents killed an American recording Border Patrol activity over the weekend.
From the London Mail [caution tabloid]:

Protesters stormed a Minnesota hotel where they suspected ICE agents had been staying amid unrest following the fatal shooting of Alex Pretti. The chaos unfolded outside of the Home Suites by Hilton Hotel in Minneapolis on Sunday night – a day after the 37-year-old ICU nurse was fatally shot by border patrol officers in the sanctuary city.
Protestors bashed windows and spray-painted the hotel’s facade, videos showed. Others chanted and paced in front of the building. Many of the mob wore masks as they descended on the scene at around 9pm, banging on garbage bins and bells.
