Authorities in Chicago are praising a jogger who spotted a man in the freezing waters of Lake Michigan over the weekend and alerted police.
"A special thank you also goes out to the individual who looked out for their fellow Chicagoan and flagged down assistance from our first responder community," police said. "As always, if you see something, say something."
In the video released by police, the jogger can be seen frantically trying to wave down cars after seeing the man fall into the water from the lakefront trail on North Lake Shore Drive.
Authorities said Saturday morning was the "coldest day of the year," as the wind chill was reported to be 5 degrees at the time.
The SWAT officers can be seen racing toward the man, with one officer taking off his jacket to place it on the snow as he attempts to reach the individual.
In the clips released by police, the officers pull the man from the lake and administer first aid as other emergency responders arrive.
The man was transported to Northwestern Memorial Hospital in critical condition, police said.
