GAINESVILLE, Fla. (AP) - A person of interest has been arrested in the case of a missing University of Florida student.
    
Gainesville police say 18-year-old Pedro A. Bravo faces third-degree felony charges of depriving a victim of a crime of medical treatment. He was arrested Monday afternoon.
    
Eighteen-year-old Christian Aguilar was last seen Thursday. Police say the two were fighting over a girl.
    
Police told the Gainesville Sun (http://bit.ly/PUqixV ) that Bravo has given them three versions of what happened. In one version, they just talked. In another, he hit Aguilar and then left. The other version has Bravo beating Aguilar unconscious before leaving him in a parking lot.
    
Police spokesman Ben Tobias says Bravo has taken investigators to several locations where he says he had been with Aguilar. Nothing was found at those locations.
