things are not looking good for Chris brown as his charges could be upgraded to a felony!

Chris brown

Sources connected with Chris tell TMZ ... the alleged victim is full of BS.  He was NOT trying to take a pic with Chris ... he was trying to get on Chris' tour bus, and Brown was simply trying to stop a trespass.  The sources say before the incident the 2 girls tried to get on the bus but they were stopped, and that's when the victim and his friend made their move.
Law enforcement sources say Chris did not appear to be under the influence of anything.
Chris and his bodyguard -- who was also arrested -- will stay in jail today.  Under DC law Brown can't get bail so he'll appear before a magistrate Monday, and until then he'll stay behind bars.  
The alleged victim tells TMZ he doesn't understand why Brown was "so homophobic" to hurl such a slur.  And get this ... the victim says he would have accepted an apology at the scene, but now he will absolutely press charges -- and he's already hired a lawyer.
Brown is still on probation in the Rihanna beating case and this could be grounds for violating his probation -- which means he could be sentenced to prison for nearly 4 years ... worst case scenario for him.

Before the incident, Chris had been hosting a party (pic below) at the nearby Park and 14th nightclub.
Chris' lawyer will ask the judge to dismiss the case on the grounds that prosecutors misused the grand jury system.
But prosecutors filed new court documents on Friday, obtained by gossip website TMZ.com, in which they explained they are taking the case before a grand jury, as they believe they have the evidence to support a felony prosecution.
They stated that the alleged victim's injuries were serious enough to require hospitalisation, which could be enough to get the charges upgraded and see the Grammy Award-winner face more significant time in jail.
If Mr Geragos fails to have the charges dropped, Chris, who was jailed last month after violating his probation stemming from his assault on Rihanna in 2009, will be forced to remain in jail until the trial begins on 17 April.
