I want to know the answer to the following question:
Who arrested Sayyid Hasan ar-Rida al-Mahdi as-Sanussi?
All the background I'm provided with is that "Khweldi Hameidi was sent to arrest crown prince Sayyid Hasan ar-Rida al-Mahdi as-Sanussi, and force him to relinquish his claim to the throne.". Is that enough to answer the question?
