Toronto police were called to a downtown train yard early Monday morning, after getting a 911 call from a man whose leg was being dragged along the tracks.

Staff Sgt. Ralph Brooks told that police initially received a radio call at about 1 a.m. regarding a problem near Bathurst and Dupont Streets.

At the scene, a 28-year-old man was found inside a "flat-top" train car and it turned out that his leg had dragged along the ground for about six kilometers, Brooks said.

The man was initially drinking beer with a group of two or three friends when the train was parked in the city's west-end.

When the train started to move away unexpectedly, the man's friends jumped out of the train car.

The victim, however, was too intoxicated to do the same and he ended up falling partway through the bottom of the train car as it began to move forward.

"The victim apparently slipped into this hole -- so his leg in essence is dangling through this hole and bumping the ground as the train is making its way from the far west end of the city."

At some point on the train ride the victim used his cellphone to call 911.

He suffered severe injuries to his lower leg as a result of the incident, and an initial police report suggested that it would likely be amputated mid-shin.

"Trains are not docile things, they are very dangerous things and they can inflict terrible injuries," Brooks said. "This young man has suffered a terrible injury and likely will suffer from this disfigurement for the rest of his life as a result of this."
