Thanks for the reply, one of the references I saw was here -
Peter and John Arrested
4 As they were speaking to the people, the priests and the captain of the temple guard and the Sadducees came up to them, 2 being greatly disturbed because they were teaching the people and proclaiming [a]in Jesus the resurrection from the dead. 3 And they laid hands on them and put them in jail until the next day, for it was already evening. 4 But many of those who had heard the [b]message believed; and the number of the men came to be about five thousand.
5 On the next day, their rulers and elders and scribes were gathered together in Jerusalem; 6 and Annas the high priest was there, and Caiaphas and John and Alexander, and all who were of high-priestly descent. 7 When they had placed them in the center, they began to inquire, “By what power, or in what name, have you done this?” 8 Then Peter, [c]filled with the Holy Spirit, said to them, “[d]Rulers and elders of the people, 9 if we are [e]on trial today for a benefit done to a sick man, [f]as to how this man has been made well, 10 let it be known to all of you and to all the people of Israel, that [g]by the name of Jesus Christ the Nazarene, whom you crucified, whom God raised from the dead—[h]by [i]this name this man stands here before you in good health. 11 [j]He is the stone which was rejected by you, the builders, but which became the chief corner stone. 12 And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved.”
Threat and Release
13 Now as they observed the confidence of Peter and John and understood that they were uneducated and untrained men, they were amazed, and began to recognize them [k]as having been with Jesus. 14 And seeing the man who had been healed standing with them, they had nothing to say in reply. 15 But when they had ordered them to leave the [l]Council, they began to confer with one another, 16 saying, “What shall we do with these men? For the fact that a noteworthy [m]miracle has taken place through them is apparent to all who live in Jerusalem, and we cannot deny it. 17 But so that it will not spread any further among the people, let us warn them to speak no longer to any man in this name.” 18 And when they had summoned them, they commanded them not to speak or teach at all [n]in the name of Jesus. 19 But Peter and John answered and said to them, “Whether it is right in the sight of God to give heed to you rather than to God, you be the judge; 20 for we cannot stop speaking about what we have seen and heard.” 21 When they had threatened them further, they let them go (finding no basis on which to punish them) on account of the people, because they were all glorifying God for what had happened; 22 for the man was more than forty years old on whom this [o]miracle of healing had been performed.
Sorry for the long post, new users can’t post links here!
I had assumed there was some sort of arrest that lead to him being imprisoned, but this reference didn’t sound like Rome. It could well be a misunderstanding on my part though.
