Utility crews are still trying to determine the cause of a gas leak that forced the hourslong overnight evacuation of dozens of residents in a Manhasset neighborhood, officials said Thursday.
No one was injured, Nassau County police said.
Seven customers lost gas service, which was restored by midafternoon, said Wendy Ladd, spokeswoman for National Grid.
Police said the leak on Chapel Road was reported in a 911 call at 11:57 p.m. Wednesday.
More than 60 residents from 20 homes were evacuated to the local firehouse to shield them from frigid overnight temperatures, officials said.
Police said electricity was turned off in the area as crews attempted to shut a valve to stem the flow of gas.
The area was deemed safe at about 4 a.m. -- and residents were then allowed to return to their homes.
Electrical power was restored at that time, but gas service was not, police said.
Ladd said utility crews were still on the scene Thursday afternoon, trying to determine the cause of the leak.
In addition to police, volunteers from the Manhasset-Lakeville Fire Department and emergency crews from PSEG Long Island responded to the scene.
