Simultaneously all the doors were slammed open and storming in from each of them were several red colour gang members. All of them displaying the symbol of their gang by having a sort of item or clothing in red.
As soon as they burst through the doors, the last person to enter carried with them chains and a lock. They began to tie it around the double doors, sealing them in.
“What are you doing? You're not meant to be in this school!” Mr Grey shouted at the intruder, he reached out his hand aiming to grab the lock. The gang member turned around, and without hesitation threw his fist, right into the teacher's face.
The middle-aged man fell on his backside, holding his face. It wasn’t enough to knock out the adult teacher, but it certainly had shaken him up a bit. The other teachers, seeing this, came to the conclusion that trying to physically stop them was not the best choice.
