In two separate incidents, three Saucon Valley High School students were arrested and charged with offenses related to the illegal possession of prescription narcotics, Lower Saucon Township police announced late Sunday.

All of the alleged incidents involved male juvenile students, police said.

In the first incident, police say a 16-year-old male student was found to be in possession of a prescription drug not prescribed to him. Police said the student admitted to taking the pills from another person's prescription bottle. Although lab test results are pending, police said the pills are believed to be Percocet.

In the second incident, police say a 17-year-old juvenile was charged with possession of a controlled substance and delivery of a controlled substance after it was learned that he had sold what's believed to be Percocet to another student at the school. Police say the juvenile admitted to selling the drugs and was found to have cash in his possession that was the money from the transaction.

The student who purchased the pills, who police say is also a 17-year-old male juvenile, has been charged with possession of narcotics, police said.

According to police, the sale of the drugs happened in a boys bathroom at the school.

Police say they were called to the school to investigate the incidents on Oct. 14.

Percocet is a narcotic pain reliever that is a combination of oxycodone--a controlled substance--and acetaminophen.
