After a weekend in D.C. that ended with an arrest and a night in jail, Chris Brown has checked into rehab, his rep confirms to People.

“Chris Brown has elected to enter a rehab facility,” his rep told the magazine in a statement. “His goal is to gain focus and insight into his past and recent behavior, enabling him to continue the pursuit of his life and his career from a healthier vantage point.”

No other details about Brown’s rehab stay were released. The singer, 24, was arrested on felony assault charges early Sunday morning for allegedly punching a man outside the W Hotel. Brown appeared before a packed courtroom Monday afternoon, where the charge was reduced to a misdemeanor charge of simple assault. He was released without bail and did not enter a plea; he is required to return to court Nov. 25.

Stories differ about what happened outside the hotel Sunday, when Brown was in town to host a party at the Park nightclub on 14th St. N.W. during Howard University’s Homecoming weekend. The police report says the alleged victim tried to photo bomb a picture with Brown and two women, but Brown’s camp claims the altercation started when the man tried to get on Brown’s tour bus. (Brown’s bodyguard, Christopher Hollosy, was also arrested.)

The alleged victim hasn’t spoken publicly; Brown’s attorney, former federal prosecutor Danny Onorato, released a statement: “Chris Brown committed no crime. We understand his security acted to protect Mr. Brown and his property, which he was authorized to do.”

If convicted, Brown (still on probation for hitting former girlfriend Rihanna in 2009) could face a maximum of 180 days in jail, along with a $1,000 fine.
