Pop star Chris Brown will be arraigned today on a felony assault charge in Washington, D.C., following his arrest over the weekend stemming from an incident outside a nightclub.

Brown, 24, was arrested with his bodyguard following "an altercation" outside the W Hotel at 4:30 a.m., a D.C. police spokeswoman confirmed to ABC News.

The incident happened after Brown left the D.C. club The Park at Fourteenth. Brown will be held until court later today, since he is reported to be on probation and not eligible for release until seeing a judge, a source told ABC News.

ABC News obtained a police report filed by the alleged victim, identified as Isaac Adams Parker, 20, of Beltsville, Md. Parker said he tried to get into a picture that Brown was taking with two other unidentified individuals.

In the report, Parker said Brown hurled out a homophobic slur at him. "I'm not down with that gay s***," Brown allegedly said. "I feel like boxing."

Brown then punched Parker in the face, the report added. The victim sustained swelling and bruises to his nose. Parker was transported to a local hospital.

Christopher Hollosy, reported to be Brown's bodyguard, also punched Parker in the face, according to the police report. Hollosy, 35, was also charged with felony assault and both were being held until today's court hearing.

Brown was partying earlier in the night at the club for a "Homecoming Weekend" party. ABC News affiliate WJLA reports Howard University was celebrating its homecoming, though a university spokeswoman said the party was not sponsored by or affiliated with the school.
