(AP) -- Sony says it has taken down its online PC gaming service due to a problem it found while investigating the security breach at its PlayStation service last month.
Sony Corp. said Monday on the Sony Online Entertainment website that it has temporarily suspended service because of an undisclosed issue. A spokesman says it's not due to a second attack.
The site matches up players for PC games such as "Free Realms" and "DC Universe online."
The company says it found the issue while investigating the recent security breach.
Sony executives apologized Sunday for the PlayStation Network security breach. The breach compromised the personal data of some 77 million player accounts.
