Michael Avenatti, the lawyer representing porn star Stormy Daniels in her legal battles with Donald Trump, was arrested in Los Angeles on Wednesday on suspicion of domestic violence.

Los Angeles Police Department spokesman Jeff Lee said no further details were immediately available about the incident, which happened in in Los Angeles. He said Mr Avenatti was released on bail after he was formally booked in the case.

"It will be presented to the district attorney's office just like any other case," Lee said. "They'll take a look at it and see if there's enough evidence to proceed."

Mr Avenatti, who has indicated that he might run for president in 2020 as a Democrat, denied wrongdoing in a statement issued through his law firm and in a statement to reporters outside the LAPD West Los Angeles police station following his release.
