Brown was "arrested at some point this afternoon," says LAPD detective Meghan Aguilar. Although an exact time was not available, she said Brown was arrested before 5 p.m.
The R&B star will be booked into a LAPD jail facility before being transferred to county jail, and will be able to post bail if he chooses.
LAPD public information Officer Tony said Brown was arrested with his lawyer, Mark Geragos, by his side, after a "thorough investigation" that produced "probable cause" for arrest.
The arrest came after police spent hours outside Brown's house, waiting for a judge to sign a search warrant so they could go inside and investigate a woman's claim that the trouble-plagued singer threatened her with a gun earlier this morning.
The police declined to explain what they were doing at Brown's house except to say that they were called to the sprawling mansion in Tarzana in the San Fernando Valley after a woman, still officially unidentified, reported about 3 a.m. Tuesday that Brown pointed a gun at her inside the house.
