Alleged CBD murderer requests meds again

The lawyer for a man accused of murdering a sex worker and stabbing another woman in the Sydney CBD has again called for his client to receive pain and mental health medication, saying his previous requests fell on deaf ears.

Mert Ney, 20, is charged with murder, attempted murder, wounding with intent to cause grievous bodily harm, intentionally choking with recklessness and common assault over the August 13 incident.

Police allege he killed Michaela Dunn, 24, in a Clarence Street apartment before stabbing Linda Bo, 41, in the shoulder at the Hotel CBD.

Ney was later filmed allegedly running through the city brandishing a bloodied kitchen knife before being restrained by bystanders.

He intends to defend the charges against him on the grounds of mental illness.

Ney appeared on Monday via video link at Central Local Court and had his case adjourned to October 15, with a brief of evidence to be submitted on that date. He did not apply for bail.

Ney's lawyer, Zemarai Khatiz, said his client had not yet received appropriate medication from Justice Health after undergoing leg surgery and had only been administered paracetamol.

At Parramatta Bail Court on Saturday, Mr Khatiz also requested Ney - who had repeatedly asked for medication - receive relief.

"He's suffering in custody over there," Mr Khatiz said on Monday.

In response, magistrate Robert Williams said he would again request Justice Health visit Ney and administer the appropriate medication.

Outside court, Mr Khatiz said Ney was struggling to sleep due to his leg pain.

Meanwhile, almost $5500 has been raised as of midday on Monday for Ms Dunn's funeral costs on crowdfunding site GoFundMe.
