Acts 22: 26-29

When the centurion heard this, he went to the commander and reported it. “What are you going to do?” he asked. “This man is a Roman citizen.”
The commander went to Paul and asked, “Tell me, are you a Roman citizen?”
“Yes, I am,” he answered.
Then the commander said, “I had to pay a lot of money for my citizenship.”
“But I was born a citizen,” Paul replied.
Those who were about to interrogate him withdrew immediately. The commander himself was alarmed when he realized that he had put Paul, a Roman citizen, in chains.
