Spanish police have arrested a 20-year-old man suspected of hacking a hotel booking website and reserving luxury rooms priced at up to €1,000 ($1,180; £870) per night for just one euro cent.
He was detained while staying at a Madrid hotel, where he is accused of having racked up more than €20,000 of losses during several stays.
Police said the alleged crime involved altering the payment validation system, and was the first of its kind to be detected.
Their investigation began after suspicious activity was reported by a travel booking site. It took just four days to complete - the Spanish outlet ABC reported that the suspect used his real identity to make the reservations.
According to police, the suspect is believed to have sabotaged the payment system via a cyber attack, getting the system to authorise his transaction after entering only one cent as the charged amount.
