A disgruntled Long Island Power Authority customer, demanding to know when the power would be back on and upset last night that the LIPA customer services office in Bellmore was closed, shattered the glass at the front entrance of the building and drove off, police said.
LIPA workers were still in the building at 2400 Sunrise Hwy. about 6:35 p.m., police said, when the man arrived and insisted that someone speak with him. He was told through a door that the office was closed and he would have to call an emergency number, police said.
After employees left the front entrance area to go farther inside the building, they heard the sound of shattered glass, police said, and then saw the man driving off in a car.
Mark Gross, a spokesman for LIPA, said it was the first case of vandalism directed at the agency since the powerful storm slammed Long Island, leaving thousands without electricity.
"Apparently he was upset, Gross said.
