Chris Brown has been arrested following a concert in Florida, authorities said.
A spokesman for Palm Beach County Jail said the singer, 29, was arrested for an outstanding warrant in neighbouring Hillsborough County, but was unable to say what the warrant was for.
Brown posted a $2,000 (£1,512) bond and was released, according to the spokesman.
He had been performing at the Coral Sky Amphitheatre in West Palm Beach on Thursday when he was detained.
A representative for Brown has been contacted for comment.
On Thursday night, after Brown was released from jail, a post appeared on his official Instagram page.
Alongside a picture of the star on stage, the caption read: "What's NEW????? Show tomorrow!!!"
Brown is currently performing his Heartbreak On A Full Moon Tour.
