A 15-year-old is suffering from painful nerve damage after a senior student forcibly injected a substance into his penis at their school in Nakhon Si Thammarat.
The boy and his mother, Jutamad, were accompanied by internet whistleblower Guntouch Pongpaiboonwet when they went to a hospital in Nonthaburi for treatment on Tuesday.
The boy, nicknamed Aye, is a Mathayom 4 (Grade 10) student in Nakhon Si Thammarat.
He said that on Aug 1 a senior student had forced him into a school toilet cubicle and then used a syringe to inject a substance into his penis.
Aye said that over the next few days his penis became swollen and painful, making it difficult for him to urinate.
The boy admitted to being bullied at school, but said he did not know his attacker and insisted the injection was against his will.
Ms Jutamad said she took her son to a local hospital in Nakhon Si Thammarat but was turned away because there was no specialist there. Her son was referred to another hospital for treatment when his condition did not improve.
Ms Jutamad said she then filed a complaint with police, but weeks later they appeared to have made little headway in the case.
Someone from the school had visited the boy at home and offered a gift basket along with 1,000 baht in cash as compensation.
According to Mr Guntouch, the senior student took a video of himself committing the assault and shared it with friends at the school. This added to the boy's humiliation.
A doctor at the Nonthaburi hospital said some nerve tissue in the youth's penis had been permanently damaged and he needed complex treatment.
