as a teen in london - this sounds almost definitely like the bloods gang, or one of the smaller gangs inside that. infact, red bandannas with aerohats mean their in the gang MDP = most dangerous persons. this is the most dominant over here and have been rumoured to be responsible for the recent stabbings of two teenagers in the hammersmith area. if you live in london especially, have a word with them. gang life is portrayed to be glamourous and exciting, but the reality is really, not so sweet.
