Was in my friend car going to my nans for sunday dinner...Couldnt wait was starvin Noticed the traffic was building up and people were getting out of there car. Could hear people shouting got close saw tesco security guard and a customer trying to pin this guy in a white top up against a wall. But another two men were stopping them... So i thought he must of stolen some thing. I saw the ***** in the white top trying to bite the security guard in the face and could see they need some help. There were a group of 3 young men looked like rugby lads built like **** house's just standing there So i decided well no one going to help every one was too busy recording it or just watching. As i got closer saw the guy in the white top headbutted the tesco customer and bit him on his arm to which blood dripped down the guy had blood around his mouth. Rushed over grabbed the guy by his right arm and just twisted his **** up and pu it into a lock and pushed the guy face against this metal shutter. As i thought he not landing that melon head on me or spitting on me To which he said 'please dont hit me bruv'. Security guard asked who i was and said thanks. The guy in the white top friends were getting close so i told them to move back away from me. Told the guy you can either calm down and come in the shop or i'll put you to the floor. He agreed to go in the shopping and said i know i've done some thing stupid and im sorry. Kept saying he was really sorry, Said dont say sorry to me say sorry to the innocent staff member and other customer you attacked. As we got closer to the shop i could tell he was thinking about having another go at getting away. His body language gave it away so tighted my grip, so did the security guard and customer. Got him into a room where he deicded to tell me 'Your ******* rude you are'. Didnt answer the dumb answer just looked at him. Asked the guard and customer what happend he tried to steal a sandwich but once confronted by another tesco customer acted quite aggressive and hit him in the face qutie a few times. Before trying to bit him i nthe face and dig his eyes out!! his two friends were also hitting the security guard and the customer trying to get them off him. The guy got bit twice really nasty ones aswell all bruised around it and flesh missing! Said 'He was thinking about letting him go once he bit him, and didnt think they could hold him for any longer as the other two were getting involved'. Felt really bad for the guy because i saw him take a few good punch's to the face. Duty manager from store came in teh room and said if you just came back in once we asked you to we wouldnt of called the police and just banned him from the store. By this time the police had turned up and before saying any thing stuck in him hand cluff's and told him to face the wall. Explained what happend and you could see the police officer was shocked all that over a sandwich. Anyway left them with my information and went but i was really pissed off wantd to batter the sh*t out of the guy who does he think he is doing this and then telling me im wrong for getting involved and im rude. Couldnt belive how many people were just standing around and not helping there were some big men there and they just stood there watching two innocent people taking a beating. Security guard said its his third time trying to steal from the store.I just couldnt believe what i was seeing the guy was acting like a wild animal. What do you think will happen to him now?
