MINNEAPOLIS (AP) — Already shaken by the fatal shooting of a woman by an immigration officer, Minnesota’s Twin Cities on Sunday braced for what many expect will be a new normal over the next few weeks as the Department of Homeland Security carries out what it called its largest enforcement operation ever.

In one Minneapolis neighborhood filled with single-family homes, protesters confronted federal agents and attempted to disrupt their operations by blowing car horns and whistles and banging on drums.

There was some pushing and several people were hit with chemical spray just before agents banged down the door of one home on Sunday. They later took one person away in handcuffs.

“We’re seeing a lot of immigration enforcement across Minneapolis and across the state, federal agents just swarming around our neighborhoods,” said Jason Chavez, a Minneapolis city councilmember. “They’ve definitely been out here.”Chavez, the son of Mexican immigrants who represents an area with a growing immigrant population, said he is closely monitoring and gathering information from chat groups about where residents are seeing agents operating.
