An American tourist was arrested after wiping his saliva on a bank note and leaving it on top of an ATM in Phnom Penh, Cambodia, on March 25.
The holidaymaker, who was identified as 64-year-old Lewis Jeffrey Cook, was seen rummaging through his pocket then licking his finger before pulling out the $10 note.
Staff who found the cash on top of the machine checked the CCTV and noticed the bizarre behaviour.
In the current hygiene conscious climate, it sparked panic and police and medics descended on the building to disinfect the area.
The 64-year-old was later arrested and detained by police.
He tested negative for COVID-19.
Officers also said the money left on the ATM was a counterfeit note.
The Commissariat of Phnom Penh said in the statement: ''A foreigner who spat on counterfeit money and left it on an ATM near the National University of Management was arrested.
''He was taken to hospital to be tested for the Covid-19 virus and for drug testing.
He tested negative and was detained for legal processing.''
