BALTIMORE, Maryland (KTRK) -- A security guard says a man was on fire as he ran from a port-a-potty.
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.
Investigators hope to find surveillance video.
