The name of an Astoria scooter rider who was fatally struck in a head-on collision with a taxi in Long Island City last month was released by the NYPD Friday. Antonios Spyropoulos, 59, of 29th Street, was named as the victim of the Nov. 27 crash after an unforeseen delay at the Office of the Chief Medical Examiner hindered proper family notification, according to a police spokesman.
