Stormy Daniels, the porn star at the centre of a political storm involving President Trump, has been arrested, her lawyer says.

Axar.az reports citing CBS News.

Michael Avenatti, who's become a frequent guest on cable TV networks since becoming Daniels' attorney, tweeted about the arrest early Thursday.

Columbus police tell CBS News they're not aware of Daniels being arrested, and as of early Thursday, Daniels wasn't being held by the Franklin County Sheriff's Department. The club, called Sirens, would only say "no comment" when reached by CBS News.

An Ohio law known as the Community Defense Act bars any non-family members from touching a nude or semi-nude dancer, according to The Associated Press.

Avenatti told the AP the arrest was "a setup."

Daniels, 39, whose real name is Stephanie Clifford, says she had sex with Mr. Trump in 2006. He was married to Melania Trump at the time and has denied Daniel's claim.

Daniels is suing the president and his former longtime personal lawyer and fixer Michael Cohen and trying to invalidate a nondisclosure agreement she signed days before the 2016 presidential election.

Cohen allegedly paid Daniels $130,000 to keep quiet about her sexual encounter with Mr. Trump. The payment might have violated campaign finance laws.
