A peaceful protest by hundreds of people in downtown Las Vegas on Wednesday evening calling for an end to immigration enforcement raids escalated into confrontations with law enforcement.

The latest arrests suggest tensions are increasing ahead of the weekend, when more demonstrations are planned.
