Dramatic body camera video released Monday shows Chicago officers pull a 33-year-old man from the icy waters of Lake Michigan after he jumped down a high ridge of ice to rescue his dog and became trapped Sunday afternoon. Officers from the 21st District responded to Foster Avenue Beach around 1 p.m. Sunday following reports of a person in the water. After borrowing a dog leash from a woman on the scene, they carefully made their way out onto the ice, mindful that they could fall in too. "He started yelling, 'help me, help me,'" CPD Officer Miguel Del Toro said during a press conference. "We ended up crawling on our knees over the ice ridge to get to him."
