New disturbing details in the Rihanna-Chris Brown case emerged Tuesday with several reports claiming Rihanna’s injuries from Brown's alleged attack were “horrific.”

Law enforcement officials took pictures of the singer and the photos show major "contusions" on her face, including a split lip and a bloody nose, TMZ reported. In addition, she reportedly has "bite marks" on one arm and on several of her fingers.

According to the Los Angeles Times, Rihanna is cooperating with detectives in the case against Brown, who reportedly left Los Angeles on a private plane to an undisclosed location.

Los Angeles Police Chief William Bratton said Brown received no special considerations before his arrest or when he was booked. "We dealt with him like we deal with everybody else," Bratton said.

Brown is now scheduled for an arraignment in the first week of March.

Prosecutors said they want more evidence from police before determining whether to press charges against Brown. Police presented a case regarding him on Tuesday, but did not release any of its details, Los Angeles County District Attorney spokeswoman Jane Robison said. She said the office would have no further comment on the case.

On Sunday night, when Brown was supposed to deliver a prime-time Grammy performance, he was instead being processed in a Los Angeles police station on a charge connected to an alleged assault on a woman that FOX 411 first reported was his girlfriend Rihanna, the 20-year-old pop princess.

Brown was booked on a suspicion of making a criminal threat after he and then-unidentified Rihanna had an argument that escalated into a fight in a rented Lamborghini in a ritzy Los Angeles neighborhood, according to police. Rihanna and Brown pulled out of the Grammys hours before the Sunday telecast.

Fans were shocked to learn of the fight between the young couple, and the news of 19-year-old Brown’s violent outburst seemed a stark contrast to his wholesome image.

By Tuesday, Rihanna had canceled her appearances for the rest of the week, backing out of a concert in Malaysia scheduled for Friday.

The fallout for Brown could prove to be devastating for his career, as female fans will likely find the image of Brown striking his girlfriend with his fists hard to forget.

"If it's true, his career is probably over," said Billboard magazine's editorial director, Bill Werde, although he cautioned that "it's important to withhold judgment until all of the facts are known."

Tracey Ford, the editor of AOL Music's hip-hop/R&B site, TheBoombox.com, said fans are shocked over the allegations, adding that Brown's career has been centered around his "squeaky clean image."

There was immediate fallout from Brown's arrest Monday, with Wrigley stopping all advertising and marketing campaigns tied to Brown, who had been their Doublemint gum pitchman. The singer also withdrew from planned appearances at the upcoming NBA All-Star Game, scheduled for this weekend in Phoenix, NBA spokesman Tim Frank said in an e-mail.

"Wrigley is concerned by the serious allegations made against Chris Brown. We believe Mr. Brown should be afforded the same due process as any citizen," the company said in a statement. "However, we have made the decision to suspend the current advertising featuring Brown and any related marketing communications until the matter is resolved."

As for Rihanna, she will likely emerge from the incident with more fans, and sympathy, Ford said.

"It might actually help Rihanna, to a certain extent," she said. "She's definitely being viewed as the victim at this point."

Several stars have already spoken out on behalf of the beautiful singer — who is a spokeswoman for Covergirl cosmetics.

On Ryan Seacrest’s KIIS-FM radio show, hip-hop artist Kanye West said he was devastated at the news of the alleged assault.

"All I want to say is, it's so devastating," West said. "Just as a person, I don't care how famous she is or even if she just worked at McDonald's ... [abuse] should never happen. It should never come to that place."
