This Cheney had been one of the four men in black, and they had most likely been there to see Thomas.
Luke said, "Selina, call Deputy Chief Thomas. I have his office number in my phone."
Selina did as told. A short while later, the call connected, and after a short conversation, she turned on the phone speaker and placed the phone in front of Cheney.
Cheney spoke quickly. "Deputy Chief Thomas, this is Agent Charles from the FBI. I was there when our head, John, went to see you. We're currently trying to arrest the suspect. Can you get your officers to provide us support?"
Thomas asked from the other end of the phone, "Where's your head? Get him to talk to me."
Thomas was quite helpless himself as he had never spoken to this Agent Charles before, so he didn't recognize the voice.
