That man then collapsed and died Sunday afternoon outside M&T Bank Stadium, the home of the Ravens, in Baltimore.

Three portable bathrooms, in a parking lot, were destroyed in the fire.
It's unclear whether the man was inside one of the restrooms when he caught on fire, or if he was just walking by.
