Saguru was fairly certain he was going into shock. He'd tagged KID with a listening device during the heist and it hadn't been immediately discarded, so Saguru guessed his arrest-attempt-distraction had been sufficient for KID to overlook the small device. He'd intended to use the device as a way to prove that Kuroba was KID, although he knew it was unlikely the thief or his accomplice would say anything incriminating. Instead, Saguru was listening to an unknown criminal attempt to dragoon KID into giving away tonight's target by threatening to kill the thief (again?!) if he refused to cooperate.
A/N: Prompt word: dragoon- to force into submission or compliance especially by violent measures
