While Daniels was performing Wednesday night at Sirens, a strip club in Columbus, some patrons touched her in a "non-sexual" way, Avenatti told The Associated Press.
"Why were undercover officers at her show to begin with???"
He said his client was accused of allowing a patron to touch her while onstage in a "nonsexual manner".
The charges were subsequently dropped.
"This was a complete set-up", he said.The group proposed the legislation as a state statute, allowing the General Assembly to pass on legislation that didn't require a public vote, according to a report. Daniels allegedly made her way toward two detectives, leaned over and grabbed their faces.
Another detective who was standing back by the bar said he witnessed the "criminal activity".
The law refers to someone "who regularly appears nude or seminude" at a club.
We expect her to be released on bail shortly.
Daniels' arraignment is scheduled for Friday at Ohio's Franklin County Municipal Court.
He says he's confident that she'll be cleared of all charges. He said she would probably leave the state later in the day.More news: India vs England 1st ODI at Nottingham

Avenatti blasted the arrest as a "politically motivated sting" and a 'ridiculous use of [police] resources'. Hours before her performance, Stormy retweeted a promotional flyer from the club, which can be seen below.
Avenatti told MSNBC he has been in touch with the prosecutors, whom he described as "incredibly professional". Court records show Daniels posted $6000 bond. Unlike many other news organizations, we have not put up a paywall.
Columbus police said Daniels' arrest wasn't a first.
A Columbus police spokeswoman didn't immediately respond to USA TODAY's request for comment.
"It reeks of desperation", he tweeted. Avenatti promised to "vehemently contest all charges".
The Columbus Dispatch reported that the law, in effect since 2007, is seldom enforced.
Adult film actress Stormy Daniels speaks at an event in West Hollywood, Calif., on May 23, 2018. "We will fight all bogus charges", Avenatti tweeted.
"I deeply apologise to my fans in Columbus", the statement read.
Earlier this week, Daniels performed in Washington, D.C., at the Cloakroom, minutes before President Donald Trump announced his Supreme Court nomination. He was married to Melania Trump at the time and has denied Daniel's claim.
