About 10 students reportedly fell ill after drinking free beverages that were found with suspicious pinhole marks near a sports ground in Hong Kong, prompting a police investigation.
Students reportedly posted messages on social media claiming that free bottles of a sports drink had been handed out during lunch on Wing Ting Road, a short distance from the Hammer Hill Road Sports Ground, where a Kwun Tong secondary school was holding an athletics meet.
Some students later noticed what appeared to be pinhole marks on the bottles, and a parent called police at 2pm, a force spokesman said.
Officers visited the site to investigate. Plain-clothes officers were seen searching rubbish bins outside the sports ground and removing plastic bottles for examination.
