A video (below) has surfaced online showing a man assaulting a woman in front of a small group of people.
The video's caption indicates that the woman is the man's girlfriend, and that his violent behavior is the result of her having cheated on him.
The woman can be seen standing in a doorway as the man confronts her about her alleged infidelity. As she attempts to respond, he smacks her across the face -- hard. He then smacks her again when she walks toward him.
Surprisingly, none of the six or seven onlookers, including one who looks to be a security guard, intervene on the woman's behalf.
The short clip, which has been viewed almost 50,000 times on YouTube, ends with the woman standing with an exasperated look on her face as the others stare at her.
One user on FlyHeight said: "Why would you hit someone who cheats on you? Obviously, you were not good enough. Grow up and move on. Stop being a crybaby!"
It is not known whether she filed any charges.
