You are walking the beat on foot patrol when you notice several juveniles standing on the street corner. As you continue to walk in their direction, you clearly observe one juvenile hand the other money in exchange for a clear baggie containing a white powder. You announce yourself as a police officer and tell them not to move. They begin to run and you give chase. You catch one of the juveniles and take him into custody without further incident. You conduct a lawful search of the juvenile and find a wad of cash and 5 small clear baggies containing a white powder (later to be confirmed as cocaine). During your search, you also notice a tattoo on the juvenile’s neck that instantly tells you he is a member of the local gang.
