A life-sized holographic police officer has been installed in central Seoul in a bid to deter crime.
The hologram is projected every two minutes from 19:00 to 22:00 in Jeo-dong Park, an area which is busy at night with nearby bars.
Police say crime rates in the area have dropped approximately 22 percent since the installation, prompting them to consider roll out in other areas.
The BBC’s Yuna Ku visited the hologram to see what people think.
