People borrowed my money and didn't pay it back. I threatened to hit him if I didn't pay him back. He accused me of intimidation! What will the police say?

If there is evidence that you really threatened, the police will warn you, fine you or even detain you. Generally, it won't be as serious as being detained by a fine, unless you ignore the police warning and threaten each other many times.

As for his failure to pay back the money, it is a civil dispute, not a matter for the police, but a matter for the court. The police handle cases according to the public security administration punishment law, and the courts mainly handle cases according to the general principles of civil law, civil procedure law and criminal law. If you have proof that he really owes you money, you can sue him. Including SMS, WeChat chat records, e-mail, general recall, transfer records and other electronic evidence. However, prosecution is also troublesome, which can drag on for three or four months to one or two years. Ask him for it and strive for a peaceful solution.

Not easy to answer. Remember to adopt your brother.
