Redwood Falls police say 16-year-old Thunder Wambade Brothersofall was swimming with several other juveniles in the Redwood River Sunday when he was caught in a current and swept away about 6 p.m.

Crews began searching the river and sent up a drone and a plane from the State Patrol but could not locate the teen. The search resumed Monday morning.
