Parents from the elementary school where both Scott Baio's and Nancy Mack's children study are outraged over an alleged assault that took place during a school function.

Baio filed a police report accusing the wife of Red Hot Chili Peppers drummer, Chad Smith, of battery.

He claimed he was assaulted by Mack over his support of President-elect Donald Trump.

Baio filed a police report over the incident that took place last Saturday at their kids' elementary school event in Thousand Oaks, California.

The Ventura County Sheriff's Office is investigating the incident, but the school is also investigating and Mack could be looking at a ban from school events, sources told TMZ.

Baio reportedly told law enforcement that Mack confronted him at an event he was attending with his daughter.

Sources told the site that parents were angry over the incident and have filed complaints with school officials.

The actor claimed Mack kept asking him how he could support a man who said 'Grab them by the p****' after the pair met at the event for the school where their children study.

According to TMZ, Baio told the sheriff's office that Mack repeatedly used the notorious phrase attributed to Trump.

Baio reportedly asked Mack to stop as there were children present. He said Mack then grabbed him under his arms and began shacking and pushing him.

Sources close to Mack said she did not assault the actor and was merely demonstrating how Trump hugs a woman.

An official at the private school wouldn't say what, if any, action would be taken against Mack, TMZ reported.

'Our highest priority is the safety and privacy of our children and their families,' the school official said.

Baio's wife, Renee Baio, also repeated her husband's claims on Twitter and posted a picture of Mack taken from video she says she has of the incident.

She also said that Mack verbally assaulted their nine-year-old daughter, asking her repeatedly if she would like to be 'grabbed by the p****'.

'@TMZ NO 'hugging' she grabbed @ScottBaio HIT & SHOVED HIM TWICE PUT HER FINGER IN BB'S FACE YELLED @ HER VILE THINGS,' Renee tweeted.

Baio also claimed that she has video of the altercation.

Mack didn't immediately respond to a request for comment.

Scott Baio's endorsement of the billionaire businessman was rare in showbusiness circles, as many celebrities backed Hillary Clinton.

He had previously campaigned for Ronald Reagan in his youth.

During a speech to the Republican National Convention, Baio said: 'Let's make America again'.

He added: 'It doesn't mean getting free stuff. It means sacrificing, winning, losing, failing, succeeding, sometimes doing the things you don't want to do, including the hard work in order to get where you want to be.

'Is Donald Trump a messiah? No. He's just a man, a man who wants to give back to his country, America. A country that has given him everything.'

He described Clinton as a 'woman who somehow feels she's entitled to the presidency'.
