Five Ward Melville High School students were treated at a hospital Tuesday, and one was arrested, after they consumed brownies obtained by a classmate, school officials said.
A spokeswoman for the Three Village school district said it's not clear what was in the brownies, but the students were taken to Stony Brook University Medical Center complaining of elevated heart rates.
A Suffolk police spokesman reported that three students complained of rapid heart rates and stomach discomfort, but school officials said five students were involved. Police arrested one of the students who became sickened by the brownies because of illegal possession of a gravity knife.
In a statement issued through a spokeswoman, Three Village schools superintendent Cheryl Pedisich said district officials believe the five tenth-grade students experienced symptoms after consuming brownies supplied by a classmate.
"The district is conducting an internal investigation and appropriate disciplinary action will be taken as necessary," said Pedisich.
All five students at the East Setauket school have been treated at Stony Brook and released.
The incident lasted from 11:30 a.m. to 2 p.m., school district officials said. Suffolk County police confirmed they responded to a call about a medical incident at the high school at about 12:13 p.m. Tuesday.
