Five-year-old US boy brought fifty packets of heroine to school for show and tell on Monday, it has been reported.

The boy was wearing his step father's jacket when he pulled out 10 small packets each containing five folds of heroine from the pocket.

When it was time for his presentation in the class at the Barnum School, the boy showed the drug packets to all his classmates.

The teacher immediately secured the drugs from the boy and apprised the principal about the incident. Police were informed by the principal and the drug packets were taken to the possession of the police.

The drugs have an estimated street value of $500 (£314), according to the police spokesman Keith Bryant.

Thirty five-year-old Santos Roman, the boy's step father, was arrested on charges of causing risk of injury to a minor, possession of narcotics, sale of narcotics and possession of narcotics within 1,500 feet of a school, according to a report from Connecticut Post.

He was arrested when he came to the school looking for his stepson. On seeing the jacket lying on an empty class room, Roman grabbed it and tried to escape, Bryant told the newspaper.

Since Roman has an extensive history of drug convictions, superior court judge Earl Richard ordered him to be held in lieu of $100,000 (£62,867) bond on the request of senior assistant state's attorney Nicholas Bove.

The boy was taken to the custody of the state Department of Children and Families until other family members are being located, according to the newspaper report.
