PHILADELPHIA (CBS) – A worker was rushed to the hospital after a crane toppled over outside the Cathedral Basilica of Saints Peter and Paul in Center City Monday afternoon.

The incident happened at about 2:15 p.m. on a sidewalk outside the Basilica located at 17th and Race Streets.

Authorities say the worker was in a crane when it somehow toppled over, falling approximately 50 feet onto Race Street.

The worker, who is identified as Tommy Quinn of the Dan Lepore and Sons Company, suffered a possible broken femur and was rushed to Hahnemann University Hospital in an unknown condition, although he was said to be conscious and alert.

There were no reports of any other injuries.

Authorities are investigating whether wind caused the crane to topple over. There is also uneven pavement on that street which may also have been a factor. The incident remains under investigation.
