The word 被捕 is formed by combining the character 被, which originally depicted a covering or quilt and evolved to indicate passive voice or something happening to the subject, with the character 捕, which pictorially represents a hand (扌) apprehending someone (甫), meaning to catch or arrest. Together, they create a conceptual unit where 被 sets the passive state of "being" and 捕 provides the action of "captured", literally forming the idea of "being caught" or "being arrested".
