Police have charged 35 people following a drug detection operation at a dance party in Moore Park last night, said a media release from NSW police.

The dance party commenced at 3.30pm.

Officers attached to Surry Hills Local Area Command, with the assistance of the Dog Unit, conducted a drug detection operation during the event.

During the course of the operation, 35 people were arrested and charged, with drug-related offences, including seven charged with supply.

Some of the alleged offences included:

– 20-year-old Mary Naioko was allegedly found with 879 capsules of drugs believed to be MDMA (‘ecstasy’) on her. She was charged with supply commercial quantity of drugs and was refused bail to appear at Parramatta Bail Court on Sunday 13 December 2015.

– A 19-year-old man was allegedly found with 103 capsules of drugs believed to be MDMA (‘ecstasy’) on him. He was charged with supply indictable quantity of drugs and was granted conditional bail to appear at Downing Centre Local Court.

– A 21-year-old man was allegedly found with 200 capsules of drugs believed to be MDMA (‘ecstasy’) on him. He was charged with supply indictable quantity of drugs and was granted conditional bail to appear at Downing Centre Local Court.

According to SMH, the event, attended by about 5000 people, was organised by Harder Styles United, who billed the rave to be one of “the most spectacular and intense indoor rave arena’s HSU has ever created”.

Last week organisers used their Facebook page to warn patrons of the drug operation and remind partygoers to “take care of one another”.

Organisers have not yet commented on the arrests.

Another rave at the same venue in October ended with four apparent overdoses.

All drugs seized during the operation will undergo specialist forensic testing.

During the operation NSW police received reports that three people were treated at the scene by Ambulance Paramedics before being taken to the hospital.

One of the three, a girl believed to be aged in her 20s, remains in hospital. The other two were later released.
