DELPHI, Ind.—According to the Indiana Department of Natural Resources, conservation officers are searching for a missing four-year-old boy.

Around 6 p.m. on May 23, police responded to a report of a child being swept away in a flooded creek at Riley Park in Delphi.

Investigation findings showed that the four-year-old boy was playing near Deer Creek when a witness saw him struggling in the water before being swept away, the DNR said.

On Thursday night, conservation officers searched by boat and utilized sonar.

The four-year-old was last seen wearing a blue sleeveless shirt and blue shorts.

Officers at the scene are urging the public not to assist with the search near the water due to dangerously elevated water levels and current.
