Acid attack at Sydney sex club

A Sydney adult entertainment venue has been targeted in a twisted attack in which lubricant was switched with acid.

A 62-year-old man was arrested on Saturday after he allegedly went to one of the rooms in the Rydalmere venue in northwest Sydney and covertly filled a lubricant dispenser with hydrochloric acid.

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.
