1. Some inmates have claimed that they have been slapped and thrashed by ghosts for committing crimes.

I was lodged inside Jail No. 3 for about 15 months. When I entered the prison, I heard stories about ghosts. I thought I was being bullied. A few days later, I heard unusual voices at night. However, I didn't share it with anyone. But days later, I felt as if someone slapped me.
