Sven Snusberg also known as "Seven" is from Stockholm, Sweden.
After squandering his wealth on leisure and luxury, he fled to Los Santos to escape serious debt to the national banks and Russian mafia, that he had no hope of repaying.
He may or may not be a full-fledged member of the Leanbois, but he pals around with them quite frequently, dabbling in criminal enterprises since his arrival. He often fills the role of the group's "fall guy", using himself as bait so the others can get away, and has spent quite some of his time in America behind bars.
He left the city, it was rumored he fled back to sweden.
