How did the toddler abuse at Capgemini's daycare facility come to light?

A whistleblower sent videos documenting the abuse of toddlers at a daycare facility in Capgemini's Bengaluru campus to a Child Helpline official, which led to the uncovering of the case. The whistleblower had first complained about the abuse to the supervisor, following which no action was taken. The whistleblower was, instead, fired from her job after she reported the abuse.
