Former B2K singer Raz-B underwent facial surgery on Thursday (15Aug13) after he was attacked with a bottle in China. The 28 year old, real name De'Mario Thornton, was performing at a nightclub in Zhejiang when a fight broke out in the crowd. The star allegedly tried to break up the altercation when he was smacked in the face with a glass bottle. Raz-B was arrested, along with the two warring crowd members, but subsequently released without charge. He required a surgical procedure to treat a severe gash to his lip and received four stitches, telling TMZ.com, "F**k this s**t hurts. I have a f**king hole in my lip. Thank God I made it to the hospital." The $5,000 (£3,333) medical bill was covered by the alleged bottle thrower, according to the website. The incident comes just over a year after Raz-B suffered a horrific accident in Shanghai last July (12), when he tripped and fell through a glass door. He underwent a five-hour operation to save his hand after the broken glass sliced the tendons in his wrist.
