HEMPSTEAD, Long Island (WABC) -- There are disturbing allegations of what is being called 'extreme hazing' at a Long Island University.
A former Hofstra student says members of one fraternity put pledges in cages, and forced them to vomit on each other.
The pictures were featured in The Hofstra Chronicle.
The newspaper says it was a former student in the Sigma Pi fraternity who contacted the national chapter.
Hofstra University confirms that the alleged hazing occurred off campus in 2014 and 2015 with former members of the Sigma Pi fraternity.
"From what I've talked to with people, they don't really understand how it went on for so long and no one really said anything," student Connor Giblin said.
The university says it was never made aware of the alleged hazing.
Last March Hofstra officials received a letter from the national Sigma Pi chapter. It said the student's charter had been revoked but provided no other details.
Hofstra says: "The national organization refused to provide any information to Hofstra about the bases for the revocation and sent a legal letter stating, we respectfully decline to share the content of our internal process."
The University immediately suspended the fraternity from campus.
The national chapter of Sigma Pi refused to answer our questions about why it didn't notify university officials of the alleged hazing.
The fraternity's Executive Director Jason Walker said:
"We are appalled by the abhorrent behavior concerning our former chapter at Hofstra University. Upon receiving information from a person who asked to remain anonymous, Sigma Pi Fraternity International immediately revoked the chapter's charter."
"These activities should really be curtailed on campus because people from all the communities are here and it's a safety issue too," said student Shrudinder Kaur.
