Shocking photos have emerged online of a boy's badly bruised bottom after he was harshly punished by a teacher at his school in Chongqing, China.
The photos show that the boy's buttocks were clearly swollen and badly bruised.
It was the result of a harsh beating with a broomstick he received at the hands of his class teacher, after he had failed to complete his homework.
According to Apple Daily, the 10-year-old boy, a fourth year student, had returned home from school in tears on Sep 28, and seemed unable to sit normally.
His father, Mr Hu, pulled down his son's trousers to check and was shocked to find that the boy's bottom was black and his pants were drenched in blood with broken skin stuck to it.
The boy said that his teacher had called him into the office over his unfinished homework, and initially made him do 400 squats.
The teacher had then grabbed a broom and started the beating, breaking two broomsticks in the process, reported Sina News.
The teacher, surnamed Li, admitted to beating the boy.
After discovering the injuries, Mr Hu immediately took his son to a local hospital, where he had to stay for three days.
He has no lasting injuries, but the scars on his bottom are still visible, English-language news portal Shanghaiist reported.
Mr Hu reportedly showed photographs of the child's injuries to reporters, and was quoted as saying: "Look, this breaks my heart. I cannot accept that a teacher could do such a thing. The punishment was too harsh."
The boy has since recovered and has returned to school, while the teacher involved has been suspended.
In recent months a number of incidents involving children suffering brutal punishments in China have made headlines.
Most notably, a mother was detained and charged for abusing her adopted son, after a teacher posted photos of the young boy's back covered in deep scars and bloodstains.
