Children at a branch of the kindergarten chain RYB Education in Beijing have claimed they were given unidentified white tablets and injections by their teachers.

The local education committee and the police are investigating the case. If the children were given injections and medication without their parents' knowledge or consent, we hope those involved will be held answerable for their illegal deeds.

But the incident, if confirmed, is not the first of its kind. Earlier this month, there were reports that teachers and cleaning staff at the child-care center of leading travel services provider Ctrip beat the children under their care and forced them to eat mustard.
