American R&B star Chris Brown has been released without charge after being held for questioning overnight in Paris over a rape allegation, the Paris prosecutor said.

The prosecutor's office said an investigation was continuing, while Brown's lawyer Raphael Chiche said his client "energetically" proclaimed his innocence and wanted to bring a defamation lawsuit.

Earlier, Brown had been questioned by police in Paris after being accused of raping a woman in a luxury hotel suite in the French capital,

A 25-year-old woman has accused Brown, along with his bodyguard and a friend, of assaulting her in the Mandarin Oriental hotel on the night of January 15, a source close to the case told AFP on condition of anonymity.

The Grammy Award-winning singer, 29, was detained on Monday on suspicion of aggravated rape and a drug offence.

The alleged victim told police she met Brown in a nightclub near the Champs-Elysees avenue with a group of other women.

She then agreed to go back to the hotel, which is on the glitzy boutique-lined Rue du Faubourg Saint-Honore.

Following the rape accusation, Brown had responded with a comment on Instagram where he said: "THIS IS FALSE AND A WHOLE LOT OF CAP! [sic]."

Brown was pictured in the French capital last week attending shows during men's fashion week.

The singer, who according to Billboard has sold more than 100 million records, has been in the news more for his legal troubles than his hit releases in recent years.

In 2009 he was convicted of beating fellow singer Rihanna, his girlfriend at the time, who was forced to miss the Grammy Awards because of her injuries.

Brown was sentenced to five years' probation and six months of community service for the assault.

Brushes with the law

In 2014 he pleaded guilty to assaulting a fan in Washington and was accused of violence by a woman in Las Vegas.

Two years later he was arrested and charged with assault with a deadly weapon following a standoff with Los Angeles police officers, after a woman said he threatened her at his home.

And last May a woman filed a lawsuit against Brown over claims that one of his friends repeatedly raped her at a drunken and drug-fuelled party at the singer's Los Angeles home in 2017.

Brown was discovered by record label scouts when he was just a boy, working at his father's gas station in the US state of Virginia.

First identified as a rapper, he later found success with his rich singing voice, selling more than two million copies of his self-titled debut album released at the age of just 16.

Best known for hits in the mid-2000s such as "Kiss, Kiss" and "Run It", Brown has released eight studio albums, six of which have gone platinum with over one million sales.

He went off the radar following the assault on Rihanna before launching a comeback in 2011 with the new album F.A.M.E., which debuted at number one in the US charts.

He has also dabbled in acting, appearing in several films as well as teen drama "The OC."

He counts nearly 50 million followers on Instagram, where a picture posted on Sunday showed him meeting fans in Paris.

News of Brown's arrest was first reported by the celebrity magazine Closer.

An investigation by Billboard in 2017 reported that Brown was battling a heavy addiction to cocaine and prescription medication.
