Police arrested a man after he allegedly poured highly corrosive acid into a lubricant dispenser at a gay venue in Australia.
Security are said to have stopped the 62-year-old as he added hydrochloric acid into the machine at "gay and bi social club" Aarows in north-west Sydney.
They were alerted after alarms fitted following similar incidents of tampering sounded.
The suspect was charged with offences including administering a poison with intent to injure or cause pain.
Australia's Daily Telegraph newspaper said detectives had not established any motive but there was "no indication of hate motivation".
The suspect was granted conditional bail and is due to appear in court on 20 September.
A club-goer told the Australian network ABC he thought it was a "sick" thing to do.
Asked about the suspect's motive, he added: "It could be anything really. People are perverted".
On the Aarows club website, a description reads: "Aarows has now long been established as Sydney’s premier health, recreation & social centre where safe sex is permitted regardless of gender."
