All 11 are current or former students at the University of Maryland, Eastern Shore. They are charged with first degree assault, hazing and reckless endangerment, state police said.
The pledges underwent surgery for cuts and infections on their buttocks from being spanked daily with wooden paddles and canes from Feb. 8 to April 4, according to police and family members.
First degree assault is punishable by up to 25 years in prison. Reckless endangerment carries a fine up to $5,000 and five years in prison.
Kappa Alpha Psi's activities at the university have been suspended pending completion of the investigation.
The university, a historically black institution, has about 3,200 students.
The fraternity has been linked to hazing incidents at two other universities -- including one last month at Kansas State where the father of a student said his son suffered kidney injuries so severe he will have to undergo dialysis.
Kappa Alpha Psi settled a $2.25 million lawsuit in December 1996 with the family of a man who died after a beating.
PRINCESS ANNE, Md. (AP) -- Four fraternity members who allegedly participated in hazing that led to the hospitalization of five pledges were arrested Friday, and state police have arrest warrants for seven more.
