Racicot says more charges are pending, and as the investigation continues, more arrests could be made.
"Right now, the arrests made are in reference to the first assault of the single male. The investigation with the female allegedly being drugged and sexually assaulted is under investigation," the chief explained.
School officials say they are waiting for city police to finish their investigation before beginning their own.
"Too many of our students are going to suffer consequences because of the poor decisions they made," Hartman said.
The police investigation is still ongoing. Police say more arrests could follow once they have fully investigated the alleged sexual assault.
