Four former pledges of an expelled Kansas University fraternity say they were subjected to extended hazing — including sleep deprivation, being forced to eat live goldfish, and being made to roll in a pit of urine and feces.

The lawsuit filed in District Court is against the alumni corporation of Phi Kappa Theta fraternity, which was kicked off campus in March after police seized 16 kegs of beer from one of its parties.

It’s the third allegation this year of fraternity-relating hazing at KU, each case involving a different fraternity. KU has 19 fraternities.

Kevin Lampe, a spokesman at Phi Kappa Theta’s national office, said he didn’t know about the allegations in the lawsuit until notified Thursday.

“We will look at these and we will take them very seriously,” he said.

The pledges claim the hazing took place starting in August 2004.
