A very violent gang, RBK Real Blood Killers is a gang started in the east and is obviously a blood gang. This gang is extremely dangerous if you see one of the members I advise u walk the other way.
Yo you heard that kid from down the street got arrested for murder, Yea it’s so crazy I heard he was part of RBK I would not want any of my kids near any of them members.
