Paul goes to Jerusalem and gets arrested when the Jews riot: Acts 20:13–21:36

It was the beginning of the end of Paul’s freedom:

^{Acts 21:27-24} … some Jews from the province of Asia saw Paul in the Temple and roused a mob against him. They grabbed him, yelling, ‘Men of Israel, help us! This is the man who preaches against our people everywhere and tells everybody to disobey the Jewish laws. He speaks against the Temple—and even defiles this holy place by bringing in Gentiles.’

We’re told the whole city was rocked by these (false) accusations. A riot started, Paul was dragged out of the Temple and  beaten. The mob would have killed him if the Roman guard hadn’t intervened:

^{Acts 21:35-36} As Paul reached the stairs, the mob grew so violent the soldiers had to lift him to their shoulders to protect him. And the crowd followed behind, shouting, ‘Kill him, kill him!’
