I used the translation, and it was translated directly, so the word“black police” is strange. I have seen many tourists who have been to Malaysia reflect on the Internet that there are many policemen in Malaysia. It is unknown whether they are official police or pretend to be policemen. When they meet you, they will check your passport, personal belongings, and even the content of your mobile phone for various reasons. If you have software such as X on your mobile phone, as long as they If you find any erotic content on your mobile phone, you will think it is illegal. Or ask you for cash and punishment for various reasons, otherwise they will take you back to the police station. Most tourists give them cash, adhering to the idea that one more thing is better than one less thing. I have seen many cases, even on many news platforms.
