NEWTOWN, Pa. - Four boys at Council Rock North High School were rushed by ambulance to St. Mary Medical Center today believed to be under the influence of an unknown substance, possibly drugs in mysterious pink pills.

Township police here were analyzing "pink pills" believed to have been taken by the students, who "displayed erratic behavior," according to police spokeswoman Jean Tanner.

It's known that a generic form of OxyContin is made in pink pills.

"The parents of the involved students were notified and responded to the medical center," Tanner reported. "The situation will be investigated and charges may be filed ..."
