SOMERSWORTH, NH (CBS) – A toddler is being treated for injuries suffered when a gravestone toppled onto her and pinned her legs, according to police.

The accident happened Wednesday morning at a cemetery in Somersworth, New Hampshire.

The girl was there with a daycare group playing hide-and-seek.

Police say the weight of two children hiding behind the large grave marker apparently dislodged it and caused it to topple.

It took two officers and a firefighter to lift the stone.

The girl is expected to recover from her injuries.
