NEW ORLEANS – Prosecutors are not pursuing criminal charges against seven Tulane University fraternity members accused of burning pledges with boiling water and pepper spray during an initiation.

The Orleans Parish district attorney's office would not say Tuesday why it decided to drop the criminal charges. Three other fraternity members still face felony battery charges.

The district attorney's office would not say whether it would pursue charges in those three cases. A court hearing is scheduled for Wednesday.

In May, 10 members of the Pi Kappa Alpha were booked on charges of aggravated second-degree battery. Police said two students were treated for severe burns after they were scalded with water from hot crab boil.
