TRENTON - Police say a kindergarten student in Trenton brought 30 packs of heroin to school.

Police were called Monday to the International Academy of Trenton.

Police say a teacher thought the 5-year-old was playing with a candy wrapper when she looked in his lunchbox and found 29 other packets of the drug.

The boy was taken to a hospital, where he tested negative for opiates.

Police are trying to determine where the child got the drugs. No one has been charged.

It's unclear who is currently caring for the boy.
