Arthur was locked in the Radley's house because his father thought it was a disgrace to send him away.
<u>Explanation:</u>
Arthur Radley who was also known as Boo Radley was locked up because he was involved in a crime. The crime that he had committed was that he along with his friends had stolen a car and then he had also locked up the officer in the courthouse.
