A 29-year-old woman is dead after she fell from the rooftop of a building at the University of Toronto early Thursday morning.

Police say the victim and a man were possibly ghost hunting and were jumping from one part of the building to another at 1 Spadina Cres.

The man made it across but the woman fell three stories to her death down to the inner quad of the building, police say, adding that the pair had been drinking.

Investigators also say the pair are not believed to be current students.

The woman was taken to hospital where she was pronounced dead. Police say they don't suspect foul play to be a factor.
