Some Chinese micro-bloggers are demanding a crackdown on foreign criminal activity in China.

Chinese social media is buzzing about a British national who appears to have sexually assaulted a young Chinese woman on a street near Tiananmen Square on Wednesday evening. A bystander helped pull the assailant off the victim, who'd screamed for help.



The assailant, whose name has not been disclosed by Chinese authorities or the British embassy in Beijing, was reportedly drunk.

The assault, and the assailant's subsequent beating by Chinese passersby, were videotaped and posted online by a Sina Weibo micro-blogger, where it was distributed over 10 million times just on Youku, the Chinese YouTube.

The video shows the final moments of the assault against the victim, as well as the assailant being beaten and subsequently lying unconscious on the ground.

One off-camera voice shouts, "F**k your mother. This dirty [expletive] foreigner. How dare you try this crap in China!"

The Sina Weibo micro-blogger who recorded the incident also captured several photographs of the assailant ogling and harassing other women on the Beijing subway system.
