TAMPA — University of South Florida police are investigating an alleged sexual battery early Sunday at Epsilon Hall, which houses 240 freshmen.

The woman who reported the rape knows the suspect, according to police. The investigation remains open. Epsilon Hall is co-ed by suite, with eight single-sex students sharing an individual suite, according to the USF website.

It is the second alleged rape at the university in the last three weeks. On Sept. 19, a woman reported an attack at her residence, Kappa Hall, also co-ed suite-style housing for freshmen. In that case, the suspect was a stranger, described as a white male, 18 to 22 years of age, close to 6 feet tall and 180 pounds with a muscular build and short black or shaggy brown hair.

Anyone with information about either incident can contact university police at (813) 974-2859 or (813)974-2628.
