BROOKLYN - Repair crews worked through the night fixing a gas leak in Dyker Heights.
It happened on 64th Street around 9 p.m. yesterday.
Officials say 64th Street near 11th Avenue was still closed to traffic this morning as crews worked to repair the damaged gas line.
Repair crews evacuated residents from four buildings last night after tests revealed high levels of carbon monoxide. However, all residents were let back into their homes a short time later.
National Grid was on the scene all night along with the Office of Emergency Management.
