Acts 4:1-3
While Peter and John were addressing the people, the priests, the chief of the Temple police, and some Sadducees came up, 2 indignant that these upstart apostles were instructing the people and proclaiming that the resurrection from the dead had taken place in Jesus. 3 They arrested them and threw them in jail until morning, for by now it was late in the evening.
