Just as Chen Nan was puzzled, those eight police officers had already rushed into the classroom.
One of the middle-aged officers was holding a photo, pointing at Chen Nan, and said, "It's him, no doubt, Chen Nan!" Then he waved toward the officers behind him and shouted, "Surround him."
At the command, seven armed officers moved swiftly, instantly rushing over and surrounding Chen Nan: "Don't move."
Chen Nan glanced at the officers around him and then at the middle-aged officer, growing more puzzled.
He scratched his head and was about to speak when his hand had just come down from his head, one of the officers surrounding him barked, "Don't fidget, hands on your head and squat down!"
Perhaps the commotion these officers made while coming up the stairs was significant, and now the classroom was surrounded by students, all peering in through the windows.
Chen Nan turned his head to look at the shouting officer: "What are you yelling for, is your brain sick?"
