Police in Thai capital Bangkok are to be punished for breaking police rules by being forced to wear one of these armbands for several days.
Police officers caught littering, parking in a prohibited area, or arriving late — amongst other misdemeanors — will also be forced to stay in the division office with the deputy chief all day, said Police Col. Pongpat Chayaphan.
"Simple warnings no longer work. This new twist is expected to make them feel guilt and shame and prevent them from repeating the offence, no matter how minor," said Pongpat, acting chief of the Crime Suppression Division in Bangkok.
"Hello Kitty is a cute icon for young girls. It's not something macho police officers want covering their biceps," Pongpat said.
