Indian Business Association, which had organised the parade, said it has constituted an inquiry, headed by New Jersey Superior Court Judge Richard Plechner, and will file the case after the inquiry is complete, IBA sources said.
Basu was invited to lead the Independence Day parade in Edison and some 10,000 people had collected to watch the event.
But Basu came late and charged that she had gone through harrowing experience at the hands of persons sent to bring her from a New York hotel to the venue of parade.
She said she had gone back to hotel and decided to return and speak frankly about the humiliation she suffered in the Limousine sent to bring her to Edison.
After hearing her, dozens of people left and did not participate in the parade. She claimed she had received some bruises, which were photographed but did not file any case.
