Long Island Democrats are furious over recently surfaced video of an ICE agent ramming a handcuffed detainee’s head into a brick wall during an arrest last month. Isai Santos Caceras, 35, was being dragged away by US Immigration and Customs Enforcement workers and resisting arrest when one of the agents got visibly frustrated. He shouted that Caceras was trying to trip him and then lowered the detainee’s head and drove it directly into the brick wall of a Hempstead Village supermarket, according to video footage posted online by activists from Islip Forward.
