Security guards in a southern Chinese city stripped and shaved the head of a man they found illegally posting advertisements on walls to earn a bit of money, a domestic newspaper reported Tuesday.

The victim, Xiao Liu, a 17-year-old migrant worker from the impoverished central province of Henan, was stripped to his underwear by about 10 men in Dongguan in the southern province of Guangdong, the Beijing News said.
