re: Someone stole my PS4

Here's a link to PS Network website. LINK

You need to change your password and deactivate your stolen PS4 so the thief cannot use any content on the system and doesn't make purchases using your account.

Here's direct contact information for Sony...

If you have the serial number, it is possible to file a police report, provide that number to them, and even give them Sony's phone number to coordinate a search. However, Sony doesn't usually cooperate. It's crappy, but it is what it is. I can say Sony HAS cooperated and helped recover stolen products before. The serial number for your system should be on the box it came in if you still have that. If not and you didn't write it down, you're probably SOL.

Best of luck.
