EAGLE, Colo. (AP) -- Kobe Bryant's attorneys dropped another bombshell Wednesday, saying they have "compelling evidence" that the NBA superstar is innocent of rape and accused prosecutors of ignoring it.

The defense said tests of underpants worn by the 19-year-old resort employee Bryant is charged with assaulting found "other substances" from a "source" other than the Los Angeles Lakers guard.

The details were released in a court filing as Eagle County Judge Frederick Gannett met with attorneys in the case to decide whether the rest of Bryant's preliminary hearing will be open to the public.

The hearing will determine whether Bryant, 25, will stand trial on a felony charge of sexual assault. He has said the sex with the Eagle woman was consensual.

Last week, the hearing began with graphic testimony from the lead investigator, who said Bryant attacked the woman from behind and raped her over her protestations.

The defense then suggested in open court that the accuser may have had sex with other men in the days before the June 30 hotel room encounter with Bryant. Prosecutors responded by asking for the hearing to be closed -- a requested ridiculed by the defense in Wednesday's court filing.

"Now after damaging information about Mr. Bryant essentially unchallenged by cross-examination has been heard in open court and distributed worldwide as the prosecution intended, the prosecution now seeks to close the hearing," defense attorney Hal Haddon wrote.

"The defense never wanted this hearing to be open," he added. "Now that it has begun in open court ... Bryant's right to a fair trial will be eviscerated if the prosecution is able to achieve what it clear intended all along."

Haddon then accused prosecutors of deliberately misrepresenting blood evidence found on the panties.

"The clear implication of this testimony was that the accuser was bleeding due to the alleged sexual assault," Haddon said. "The prosecution deliberately mischaracterized that evidence by consciously failing to put before the court all of the evidence concerning those panties."

The defense said that evidence had been given to Gannett, under seal, and it provided "compelling evidence of innocence."
