I watched the press conference the police gave and they didn't mention Sony at all until a journalist asked about the Sony hack and the police officer answered the arrested could be related to it, maybe, but that they didn't know if they were, and that they weren't going to charge them with anything related to it unless they found out they were involved. So no, they didn't get "arrested over Sony Hack".
This three guys were arrested because they were the administrators of a chat Anonymous used for their online meetings. They could be related to some DDoS attacks in Spain, though it's not clear how, and that's why they got arrested. They're not being charged with data stealing so far, just regular DDoS attacks against banks, political parties, foreign governments and similar organizations. Not confirmed relation with the Sony hack so far.
Linkbait: "Mark Rasch, former head of the US Justice Department's cyber crimes division, said he would not be surprised if Anonymous turned out to be linked to the Sony data breach..."
