The classmate was handed the bag by the girl shortly after giving birth to the baby girl in the school.
Doctors in Kuala Terengganu found out about the birth when the girl sought medical treatment complaining of abdominal pains, leading to her confession that she had put the dead infant in a school bag and given it to her friend.
"They found the dead baby girl in the bag. The friend was traumatised when she learned that she had been carrying around a bag containing a dead baby," ACP Manoharan told reporters, adding that the post-mortem showed the baby was successfully delivered, but suffered bruises on the head and had water in the lungs which led to her death.
