Police said an Indian Coast Guard (ICG) helicopter airlifted them after they remained stranded on the rock for several hours in the middle of the overflowing river near Bari Kachigam village at Umargam tehsil.
"These persons were searching for the body of a boy from the same village who drowned in it a day ago. However, as the rains continued, the water level increased in the river even before they could come out, and were thus left stranded there," Valsad Superintendent of Police Prem Vir Singh said.
According to the officer, the rescue operation involving the helicopter went on for nearly an hour.
