A Tribeca resident should thank Lady Luck for suffering only minor injuries after falling 30 feet through a sidewalk grating on Murray Street on Saturday. According to a Chinese food deliveryman who witnessed the incident, Vincent Riggio, 59, exited the OTB parlor near Murray Street, "He had a cigar, he stepped on the platform and he fell. I looked down the hole. He was down there, squatting down. There was a lot of dust."
