A man has allegedly been caught in the act of filling a lubricant dispenser with hydrochloric acid at what is thought to be a gay club.
The 62-year-old was arrested on Saturday after he allegedly went to one of the rooms in the Rydalmere, north west Sydney, venue to carry out the twisted attack.
According to the ABC, the venue was the Aarows Club, which describes itself as 'Sydney's gay and bi social club' with 'three levels of adult adventure'.
Police said security detained the man after he set off an alarm.
It wasn't the first time the venue had been targeted, and items in the room had been alarmed to warn of tampering, according to police.
The man has been charged with administering a poison with intent to injure or cause distress or pain, entering a building with intent, malicious damage and driving while suspended.
He was granted conditional bail and is due to appear in the Parramatta Local Court on September 20.
