A Perth businessman who is currently suing Married At First Sight star Lauren Dunn for defamation has been arrested for alleged possession of cocaine.

Aidan Murphy will face a Magistrates Court on October 17 for allegedly possessing cocaine on August 20, and for breaching a family violence restraining order.

Murphy, 37, pleaded not guilty to the FVRO breach, which allegedly took place between June 15 and 16, and also pleaded not guilty to the drug possession charge.

The offences allegedly took place in Applecross, the WA suburb where Murphy lives.

When Daily Mail approached Murphy for comment, he declined to comment about the alleged cocaine possession and FVRO breach.

‘Sorry, no comment. You’ll have to speak to the lawyers about that one,’ he said.

When asked to provide a contact for his lawyer, he was unable to provide it, stating: ‘I don’t have it with me. I’m not in the country at the moment.’

It comes after Murphy filed a defamation lawsuit against MAFS star Dunn, 33, over social media posts made in July.

Murphy alleges Dunn posted malicious and false comments about him on TikTok, Instagram and Facebook between July 14 and July 21.

The summons was filed with the WA Supreme Court on August 15, WA Today reported last month.

In it, the managing director claimed Dunn defamed him and, by extension, the business he works for, Unite Resourcing.

Murphy did not specify in the summons which posts allegedly defamed him; however, it is understood they have since been removed from social media.

Murphy’s lawyer, Roger Blow, filed the summons and requested that the court issue an injunction to stop Dunn from making similar posts about the Applecross man.

Murphy claimed Dunn made the posts out of ‘malice’, and Blow claims the reality TV star is also liable for defamatory remarks made by her followers.

Dunn told WA Today her posts were a reaction to negative remarks Murphy allegedly made about her in relation to her ex-boyfriend, former AFL player Ryan Crowley.

Crowley is currently facing a series of domestic violence charges related to his relationship with Dunn in 2019 and 2020.

The former Fremantle Dockers player was recently hit with six new charges, with prosecutors alleging he attacked his ex-girlfriend ‘to the point of almost killing her‘.

The 41-year-old appeared in Perth Magistrates Court on July 22 over the historical charges, which are alleged to have taken place between 2019 and 2020.

Crowley was charged with one count of unlawful assault and one count of threatening to kill.

Those charges are alleged to have taken place in September 2019.

He is also facing one count of unlawful assault, one count of intent to harm, a count of deprivation of liberty and another count of deprivation of liberty in circumstances of aggravation.

Those charges allegedly took place in March 2020.

Five of the offences were allegedly committed against his former girlfriend, Dunn.

The final charge pertains to the alleged abuse of another woman.
