The chaos associated with last weekend's Zombie Pub crawl crept onto the light rail in hours after bar close, early Sunday morning.
The melee was captured by Beth Houston on her cell phone, while she commuted home after the car she was riding on got packed with revelers.
During the course of the ride a fight involving numerous people erupted, right next to where Houston was sitting.
It is unclear if anyone called 9-11 during the fight, but one thing was clear to Houston – there were no police officers on the car.
Houston is used to wild rides while taking light rail.
"All the time I see crazy stuff on there. I've seen a guy pull a knife on another guy," said Houston.
What worries her is that she has never seen a cop, "I've never, ever seen an officer or security on that train. I've never been asked to see if I'd paid and had a ticket. Ever."
Metro Transit officials say they have security forces on the trains all the time, but stress they can't have an officer on every car, they also say the night of the pub crawl they had extra officers on duty.
"Metro transit officers ride trains every day, ride busses every day. They ride in uniform and ride in plain clothes," said Metro Transit spokesman John Siqveland.
Additionally there all call boxes on every platform riders can use if they witness crime.
"And what we encourage people to do if they do see a disturbance is use that call box on the train, call 911 or use the call box on the station platform," Siqveland said.
There was a report made at the Humphrey Station the night of the brawl that investigators believe is related to the incident Houston captured on her phone.
Investigators have other video and are hoping they can use it to identify people associated with the fight.
