ESTERO — A brewing rivalry between members of two sororities at Florida Gulf Coast University resulted in an 18-year-old Deerfield Beach girl reporting she was struck, suffering a black eye and a knot on her head.

According to a Lee County Sheriff's Office report released Monday:

At 1:23 p.m. Friday, a deputy went to campus housing where Kristen D'Agostino lives. She told deputies that at 1 a.m. Friday she and two other friends were at a restaurant on Corkscrew Road in Estero . They were walking by the bar and saw three other girls.

"D'Agostino stated she is not friends with those girls and that there has been a rivalry brewing as each group of girls is in a different sorority."

As D'Agostino and her friends passed the bar, the other girls spilled drinks on them. They began arguing, were separated and D'Agostino and her friends went to another friend's apartment in the Bella Terra community.

As they were waiting to be let in, the other girls drove up and they began arguing again.

One of the girls, a 21-year-old Naples woman who is 5 feet, 2 inches and about 110 pounds said to the 5-foot, 130-pound D'Agostino : "Come on fat blonde , right here."

D'Agostino said she wasn't going to fight and the other girl hit her in the left eye, the report said.

D'Agostino said she attempted to call 911, but was hit again in the back of the head and her head was slammed into a wall several times.

When the door of the apartment was opened, D'Agostino and her friends went inside and the other girls left.

"D'Agostino said she didn't stay on the phone with the 911 operators because she didn't know the address," the report said.

She called authorities later Friday to make a report because she had a knot on her head and the beginning of a black eye, she said.

No one had been arrested as of Monday.
