That's horrible man! Glad you're ok dude. I don't play streetball because I'm too much of a pussy, but I wouldn't have let that dude touch my ball more than once. "I'm good dude" and I would have kept my ball and just bounced. I doubt it was an accident either, he was probably trying to rob you. I work for the cops and every night I see all sorts of horrible crime reports come across my desk and a lot of times they're over even less than a basketball. Be safe dude.
