A South Korean professor's claims that his range of digital water filters could turn regular tap water into genuine Holy Water from Lourdes have brought an icy response from Seoul's police.
According to local reports, one Professor Kim - said to work at a "prestigious medical school" - had sold the devices to almost 5,000 people, making around $1.4m in the process.
JoonAng Daily says Kim claimed that he had digitally captured the healing powers of genuine Holy Water from the Catholic Shrine at Lourdes, in France.
