About receiving threatening text messages

This kind of thing will be accepted by the police, which has seriously affected your friend's daily life. Her personal safety is not guaranteed, and it has also caused psychological pressure. If she goes to court, she can claim compensation. But the police will not pursue it too much. You know why. You can try to meet that man and ask plain clothes to hide nearby. What did that man do to your friend? Arrest him immediately so that he can go to prison.
