BEIJING: Chinese police have launched an investigation into alleged child abuse at a Beijing pre-school after parents found apparent needle marks on toddlers, sparking new outrage days after a scandal at another daycare. Distraught and angry parents also reported that children were given unidentified pills at the RYB Education New World kindergarten, run by a company that started trading on the New York stock exchange in September. The Chaoyang district government said police opened an investigation after parents called the authorities on Wednesday to report the suspected abuse. Authorities declined to provide more details about the allegations. RYB apologized to parents and said it was cooperating with the police investigation.
