A 66-year old woman reportedly suffered a broken arm and injury on face after a car rammed into a crowd protesting against the immigration and customs enforcement (ICE) department in downtown Chicago on Tuesday evening . In a video which has now gone viral, on social media platforms, a maroon sedan can be seen speeding through the protesters, nearly hitting multiple pedestrians. Demonstrators were seen momentarily chasing and striking the vehicle before it drove off from the scene without halting.The woman, identified as Heather Blair, was on her way back home when the car barrelling down the street hit her, fracturing her left arm. She was taken to Northwest Memorial Hospital for treatment, Blair told CBS news.“I thought it was a violent act, because the car was accelerating,” Blair said. “It seemed like it was getting kind of heated, and we didn’t want to be involved in any violence”. The police said they are still investigating the matter.Massive demonstrations erupted in key US cities last week following a wave of immigration raids, as the Trump administration moves to deliver on his campaign pledge to deport immigrants using aggressive measures.“President Trump promised to carry out the largest mass deportation campaign in American history and left-wing riots will not deter him in that effort,” White House press secretary Karoline Leavitt said.
