A 17-year-old boy has rescued a man after the car he was driving in with his dog plummeted off a bridge and broke through the icy surface of a lake.
The incident took place in Iowa as the north and western parts of the country are frozen by an arctic blast that has brought dangerously frigid temperatures over the past week.
Thomas Lee, 83, and his dog Cooper, 6, were trapped inside the Jeep after Lee drove it off the Highway 71 bridge on East Okoboji Lake, Dickinson County, US, at around 3pm (9pm GMT) on Saturday, February 4.
