Volunteers and RCMP underwater search teams spent all day Tuesday looking for the body of a Sandy Bay, Sask., boy, but found no sign of the six-year-old.

The boy disappeared Saturday afternoon, and people in the community of about 1,000 on the shores of the Churchill River have been searching for him since that evening.

Police believe he may have slipped into some water near his home. Some children saw the boy heading toward the water's edge.

"He had been seen near his home going down a hill towards the water,"  RCMP Sgt. Carole Raymond said. "He was not seen returning from the hill."

Later, people found a set of small footprints directed toward the water, but no footprints pointed back, Raymond said.

Community members have been using boats to try to find him, with no success so far.

The RCMP underwater recovery team searched until dark Monday night and from 9 a.m. until nightfall Tuesday.

Sandy Bay is in northeast Saskatchewan, close to the border with Manitoba and about 190 kilometres northwest of Flin Flon, Man.
