Eleven members of a University of Georgia fraternity were charged Feb. 6 in connection with the hazing and physical abuse of pledges.

According to The Athens Banner-Herald, police obtained warrants for the members of the Zeta Iota chapter of Kappa Alpha Psi after determining that they struck pledges as part of the new members’ initiation.

“We began an investigation after we were provided with information by Student Affairs that someone was possibly injured during a pledge event,” University of Georgia Police Chief Jimmy Williamson told the newspaper.

The fraternity members charged in the incident turned themselves in at the Clarke County, Ga. Jail on Feb. 7, according to The Atlanta Journal-Constitution. After being booked, most had been released on $2,500 bond as of that morning, the newspaper reported.

All were charged with a single count of hazing, an aggravated misdemeanor under Georgia law which carries a maximum penalty of 12 months in jail and a $5,000 fine.

The incident allegedly took place on Jan. 27 at the home of a member of the fraternity, which does not have a fraternity house. According to the Journal-Constitution, several pledges were allegedly beaten with fists and sustained minor physical injuries but did not require medical attention.

Kappa Alpha Psi is a largely African-American national fraternity with undergraduate and alumni chapters on major college and university campuses and in cities across the country.
