Getaway Bus

When the bus I rode this morning stopped at a bus stop in the CBD, a policeman came to talk to the driver. He came up to have a look and left. He was probably looking for someone on another bus. I couldn't hear what he said to the bus driver. But I heard what the nearby passengers said. Two ladies said something like:
"Is there a suspect on the bus?"
"A suspect uses the bus as the getaway vehicle?"
"At least it's an express bus. Maybe he saw 'Express' on the bus number."
