A bold cyclist taunted US Customs and Border Protection officers in downtown Chicago, yelling “I’m not a US citizen!” This led to a dramatic street chase, all captured on video.

The intense encounter depicts the unknown cyclist approaching a group of agents on Sunday while federal immigration officers monitored the streets of Chicago.

“I’m not a US citizen! Come on!” the man is heard repeatedly yelling at the agents.

As one officer appears to walk close to him, the belligerent biker rides up the street — still making taunts — but his phone falls from his pocket.

“You dropped your phone,” one agent shouts.

As the cyclist circles back and picks up his phone, one of the agents yells, “Get him!” while around a dozen officers rush to grab him.

The agents then chase him down the street, but the cyclist was able to escape and ride off.

The footage was captured by Christopher Sweat, who said the man “made verbal comments but no physical or threatening contact.”

Authorities have not disclosed whether the man was identified or taken into custody, according to Fox 32.

Armed federal agents in full tactical gear descended on downtown Chicago for the latest immigration crackdown over the weekend.

Numerous federal troops were observed patrolling some of Chicago’s major tourist and shopping areas during the ICE operation that began Sunday afternoon.

Trump shared footage on Truth Social late Sunday of protesters harassing federal agents as he warned, “Border Patrol will take no nonsense!”

Chicago Mayor Brandon Johnson and Illinois Gov. JB Pritzker, both Democrats, blasted the Trump administration’s show of force.

It’s not immediately clear how many illegal migrants were nabbed in the Chicago operation.

The Chicago operation comes just weeks after Trump started threatening to send the National Guard to flood the city.

The scenes in Chicago unfolded after the feds began arriving in Portland, Ore., over the weekend, following Trump’s order for a military deployment there as well.

Clashes erupted outside an ICE facility as Trump confirmed he’d authorized “full force” to protect a “war ravaged Portland” and federal buildings “under siege by ANTIFA, and other domestic terrorists.”
