There is something very satisfying about this video of a woman chasing after an attacker who punched the guy sitting next to her on the London Underground (aka the "tube"). What we know from the video, which was posted yesterday on Twitter, is that a man was punched in the face, seemingly without provocation, while sitting on the subway. The man is Asian so the Independent speculates the attack may have been racially motivated.
Unluckily for the attacker, this female passenger wouldn't take the attack sitting down. When the attacker runs off the train, she quickly stands up and follows him. She then chases him down the platform yelling "call the copper." You can watch her in action here (just FYI this video contains some violence):
It seems like she might have caught up with him eventually and alerted "the copper," because a suspect was arrested shortly after the incident, according to a British Transport Police spokesman. "A 33-year-old man has been arrested on suspicion of assault occasioning ABH and using threatening, abusive words, behavior or disorderly behavior likely to cause harassment, alarm or distress," said the spokesman of the attacker, who is out on bail.
There is a lesson to be learned here: don't punch people. Especially if there is a lady present. She might punch back.
