A dive team was able to recover a man from underwater after a drowning accident in Moore Lake in Fridley.
The Anoka County Sheriff's Office says the incident was reported just before 5:15 p.m. Sunday. It happened when a father attempted to swim out to help two kids get back to shore, as they were struggling to do so on their own while using flotation devices.
