4:11 PM PT -- A rep for Florida State University has issued a statement saying, "We are aware of a matter that was investigated by the Tallahassee Police Department almost a year ago.
Because the investigation has not been closed by TPD, we cannot comment further at this time.
We look forward to a speedy resolution of the issue. There is no change in Jameis Winston's status."
Florida State QB Jameis Winston -- frontrunner for the Heisman Trophy -- is being investigated for felony sexual assault, TMZ has learned.
Law enforcement and other sources tell TMZ ... a woman filed a sexual assault complaint with the Tallahassee PD on December 7, 2012. She claims the alleged sexual assault was committed with the use of "physical force."
According to the police report, the motive for the alleged crime was "sexual gratification." The alleged victim says drinking was involved before the incident.
The police report says on the day in question, someone called the cops at 4:01 AM. When police arrived, we're told there were photos taken of the alleged victim's injuries as well as physical evidence collected.
According to the police report, the incident occurred in an apartment.
Winston is described in the police report as "muscular" and his demeanor as "polite."
Our sources say cops have already interviewed Winston.
As for the alleged offense, it requires proof that the perpetrator penetrated the victim orally, anally, or vaginally.
The investigation is "ongoing" with the police and the Florida State Attorney.
BTW ... the initial police reports lists the suspect's height at 5'11'' max ... Winston is 6'4.' That report also says the suspect has straight hair. Discrepancies aside, we have confirmed with law enforcement sources Winston is indeed the suspect.
