It comes in the wake of revelations by Fairfax Media and the ABC, which revealed that three cast members of the 2014 Rocky Horror Show allege they were abused, indecently assaulted, bullied and intimidated by the well-known entertainment personality.

Victoria Police have confirmed they are investigating allegations of indecent assault and inappropriate behaviour involving McLachlan, who will not continue in the 2018 tour of Rocky Horror in the lead role of Dr Frank-N-Furter.

A statement from producers The Gordon Frost Organisation said the company was "shocked" to learn of the allegations against its star. It is unclear who will fill McLachlan's role for the remainder of the season.

"We have spoken to Craig and have mutually agreed it is not appropriate for him to continue in the current production of the show," the statement read.

"We will be conducting a full internal investigation and will cooperate fully with authorities."

Actresses Angela Scundi, Erika Heynatz and Christie Whelan Browne have alleged that, during the 2014 tour of Rocky Horror, female cast members were abused, harassed or indecently assaulted by McLachlan, 52.

Some of the allegations suggest that, while female cast members were performing, McLachlan was touching their genitals out of the audiences' view.

He is also alleged to have exposed himself in a dressing room, as well as making numerous unwanted sexual advances off stage.

In December, Scundi and Heynatz lodged complaints with Victoria Police alleging that a number of actresses in the show were subjected to McLachlan touching their genitals, groping their breasts, exposing himself and pressing his penis against them.

"He's really calculated and very manipulative, a predator," said Heynatz, an actress and model.

McLachlan has strongly denied the allegations. In an email, he said: "These allegations are ALL made up ... I have NEVER done anything like this ... I am, and have been at all relevant times, in a stable relationship with my long-term partner."

He said the allegations "seem to be simple inventions, perhaps made for financial reasons, perhaps to gain notoriety". 

McLachlan claimed that Rocky Horror was "a confrontational musical oozing with sexuality" and that, to "make" the show, "actors have to perform certain actions, all of which flow from the show itself".

​"It's the most fun you can have in public without getting arrested," he said only last week about his reprisal of the lead role as the raunchy transvestite Dr Frank-N-Furter in the 2018 tour.

In an interview last November, Rocky Horror's creator paid tribute to McLachlan's raunchy performance "but admits they occasionally have to rein him in".

Richard O'Brien, who wrote the successful musical more than 40 years ago, told Melbourne's Herald Sun: "Craig steps out far beyond what most other performers can do ... he pushes the boundaries of both good and bad taste to the extremes, and wins.

"If most people went to the lengths Craig does, it would be offensive, but it never is with him. Of course, we have to rein him in occasionally.

"When a performer knows they've got freedom to almost do anything they want, which Craig does, sometimes you have to say: 'Less is more'.

"It's like playing tennis and the audience is on the other side of the net. You send out your performance, your jokes and your energy.

"The audience reacts ... and gives you encouragement to go further. If you're not careful, that encouragement might take you a little too far."

Before the three actresses went public with their claims, they asked The Gordon Frost Organisation to investigate their claims before the show opened in Adelaide. The women said they were fearful that the current female cast members might have to endure what they did.

However, GFO declined to act and instead threatened the women, through their lawyers, that the company might sue them for defamation.

Chloe Dallimore, the head of Equity, the Australian union body for actors, said employers and producers can no longer disregard reports of harassment and bullying. 

"For decades, it has been the case that even when harassment is reported to the appropriate people, it gets shoved under the carpet, or it doesn't get reported due to fear of job loss," she said.

"Employers and producers must have official guidelines and these must be shared and upheld. The cycle must stop now."

On Monday, Victoria Police released a statement saying: "Detectives from Melbourne SOCIT [Sexual Offences and Child Abuse Investigation Team] are investigating allegations of sexual offences dating back to 2014.

"As the investigation is ongoing, it would be inappropriate to make any further comment."

McLachlan was also famous for his starring roles in The Doctor Blake Mysteries, Neighbours and Home and Away.

Last year, the Seven network picked up the rights to the Doctor Blake series – after the ABC axed the show in March, despite it pulling in about one million viewers per episode.

The popular series – which ran for five seasons on the ABC, wrapping up in November – was set to debut on Seven in 2018. In a statement, the network said: "The Doctor Blake Mysteries, [is] produced by December Media and is in early pre-production funded by Seven and other parties. Seven has sought an urgent update from the producers."

An ABC spokesperson said there had been "no complaints made to the ABC involving any members of the Doctor Blake cast, who are employed by December Media".

A Ten spokesperson said the network had not received any complaints about McLachlan's behaviour during his stint on The Wrong Girl, where he played sleazy breakfast TV host Eric Albrectson​ for two seasons since 2016.

"If we had been, we would have acted swiftly and decisively," the spokesperson said in a statement, adding the network "will not tolerate bullying, harassment or any form of discrimination, and we expect our business partners to have the same zero tolerance approach."

On Monday night, December Media, issued a statement saying it will temporarily hold production preparations for the new series "to allow due process" in light of the allegations.

"Throughout the six years of production of Doctor Blake it has not only been an enormously popular show on air but popular with cast and crew who come back to work on the series year after year," the statement said.

"Craig has been central to this success both in front of camera and on set. It is not appropriate for December to respond to the allegations about Craig McLachlan's behaviour in relation to another production he has appeared in.

"We do not tolerate any form of behaviour, which makes anyone feel threatened or uncomfortable for whatever reason in the workplace."
