A violent mob of protesters breached a US Immigration and Customs Enforcement (ICE) facility in Portland, Oregon, on Saturday night, injuring four federal officers, according to authorities.

Portland Police said the arrests on Saturday were related to "violent activity or property destruction" during a declared riot near an Immigration and Customs Enforcement (ICE) facility.

Rioters late Saturday stormed an Immigration and Customs Enforcement building in Portland, Oregon, unleashing smoke bombs and firecrackers and injuring several federal officers before order was restored. The Homeland Security Department decried the violence, vowing to bring every single perpetrator to justice.
