First of all, you were wrong and you should not have stolen 100 yuan from the supermarket;
Secondly, the supermarket was wrong. If you return the items to the supermarket, the supermarket has no right to fine you;
Thirdly, the local police station does not have the authority to impose a fine of 15,000 yuan, and the police station generally can only impose a maximum fine of 5,000 yuan.
What to do: It’s official business, don’t be afraid. You’ve already made a mistake and you can’t hide from it. Supermarkets and police stations are just taking advantage of your fear. 100 yuan is a small problem at the police station and cannot be dealt with. A fine of 200 yuan is imposed. If the police station cannot solve the problem correctly and want to report it to the higher-level public security bureau, they are afraid.
