Just 12-years-old, but she is already involved in sex and drugs.

It seems that life has not been too kind to the Standard Six pupil, especially after she met a 24-year-old man through the messaging mobile application WeChat.

The man ended up making her his sex slave, and gave her syabu (methamphetamine) as a token for fulfilling his sexual needs.

Kota Setar police chief ACP Mohd Rozi Jidin said the matter was exposed when the victim's mother noticed changes in her daughter's behaviour.

"The mother brought her daughter to the hospital for examination, and discovered tears on her private parts, indicating that the child had been sexually active.

"It is believed the suspect had given syabu to the child. Just imagine, only 12 years old and already exposed to drugs and sex," Mohd Rozi told a press conference today.

He said the girl's mother has lodged a police report at the Kota Setar district police headquarters yesterday.

Police have identified the suspect, who has a past criminal record related to drugs.

Investigations were still ongoing, Mohd Rozi added.
