According to LoHud on May 26:

A ruptured gas line shut down activity around Hunts Lane in Chappaqua on Tuesday, officials said.

About 75 children had to evacuate World Cup Nursery School after an excavator fixing a water leak on the property accidentally hit a gas line around 3:32 p.m., New Castle police said. The children were bussed to Roaring Brook Elementary School, where they waited in the gym to be picked up by their parents, police said.

No one was injured from the leak, which Con Edison repaired. Water service to several surrounding homes was disrupted for a few hours, police said.
