Investigations into Monis began in January when the first victim came forward and police established Strike Force Yorkfield to investigate the allegations. It led to Monis' arrest at Bexley North where he was charged and later refused bail.

Police said the woman, who was 27 at the time, allegedly saw an advertisement for "spiritual consultation" in a local newspaper and contacted Monis. He told her he was an expert in astrology, numerology, meditation and black magic and advised her to visit his clinic.

The woman visited the clinic twice within a week. On the first occasion it will be alleged that Monis indecently assaulted her. A week later he is alleged to have indecently and sexually assaulted her. "The assaults are alleged to have been undertaken under the guise of a spiritual healing technique, and the man warned the woman not to tell anyone about them," police said in a statement.

The court was told when he was arrested in April that Monis was on bail after being charged in November with being an accessory before and after the fact to the murder of his ex-wife and mother-of-two Noleen Hayson Pal.

Monis, who is also a self-styled sheikh known as Sheikh Haron, was sentenced to 300 hours of community service in September 2013 after he penned "grossly offensive" letters to the families of dead Australian soldiers.
