Ivan Congreve - manager of Springfield Lodge in Camberwell, which provides homeless men aged 16 to 21 with a home and teaches them the skills to become independent - said some joined gangs because they provided an alternative family. He said: "All of our guys are from a broken family of one sort or another and that leads them into gangs. That's where they seem to be able to find the family they are looking for. They are accepted, looked after and respected in ways that they don't feel they get from their family."
