A 62-year-old man was killed today when he apparently tried to board a SEPTA bus through the rear door and was dragged under the vehicle in North Philadelphia, police said,

The victim, identified as William Bogl, of F Street near Allegheny Avenue in Kensington, was pronounced dead on arrival at Hahnemann University Hospital.

Police said initial reports indicated he tried to board the eastbound Route 15 bus on Girard Avenue at North 8th Street about 9:25 a.m., but the door closed and his arm got caught.

The bus then took off and he was dragged under the vehicle and run over, police said.

An investigation is under way.

SEPTA said a bus was operating in stead of the Route 15 trolley because of work in the area.
