A viral video taken by a passenger on a San Francisco area train shows a man verbally and physically attacking a fellow passenger, an Asian man.
The video was shared on Facebook on Tuesday, and at the time of this writing, has been viewed over 1 million times on the social networking site.
What was in the video?
The victim, Charles Wu, told The San Francisco Chronicle that he'd asked the man to stop using racial slurs in the Monday night incident.
"No one was saying anything and it was a BART full of people," Wu said. "I had enough, so I told him, 'Sir, you need to stop talking.'"
In the video, the man can be seen approaching Wu, and using more racial slurs while antagonizing him.
"I’ll punch you down," Wu's attacker can be heard saying before slapping Wu.
Wu remains calm after being struck the first time, but begins to lose his patience after the man hits him a second time.
After the second hit, Wu can be seen rising from his seat.
Another passenger intervenes and urges Wu to remain calm.
"He’s drunk, man, he’s not even worth it," another passenger says.
Facebook user Wiseley Wu wrote, "[E]ven in bay area, racism like this still exists. (I did call the BART police, but the guy left before they arrived) edit: I was merely the person filming it, not the guy being insulted. I wish I were as brave as him. edit2: clarification - this started because the old man was using the n-word repeatedly on the train, and the Asian guy decided to step in and tell him to stop."

What did police have to say about the incident?
According to The San Francisco Chronicle, the attack occurred about 10:10 p.m. on Monday.

Authorities believe the attacker got off the train before they arrived on the scene.
BART officials are investigating the incident. No arrests have been made in the case.
