An internal investigation conducted by a Baltimore-area university shows that its cheerleading team hazed new members by giving them alcohol and telling them to wear adult diapers.

The information is contained in a report obtained by The Associated Press through a Freedom of Information Act request. Dated April 17, it was first published by The Baltimore Sun.

The report says the hazing took place on July 31, 2013, when new freshmen were invited to an off-campus apartment during cheer camp.

According to the report, veteran cheerleaders blindfolded freshmen team members, gave them a choice of doing a shot of liquor or funneling a beer, and instructed them to wear adult diapers over their cheerleading shorts.

University officials ordered an investigation last August after receiving an anonymous call about the hazing.
