It got damaged there because... it trespassed Sweden's national waters. I didn't say they didn't do it, I say it's hypocritical to make such a hype over it when there are hundreds such incidents per year, every year by Russia that nobody cared for, for decades and that when others do it, it's still ignored. And I don't just talk about Greece-Turkey infringements here. USA also "comes close" to national borders of Iran quite often. And actually bombed inside Pakistan without warning a few times (although at least they killed OBLaden that way). Look at what importance China places to other countries national borders.
But suddenly, NOW, it's important that Russia did it. When Russians were doing that for years as the sources of both of you show... nah, then it wasn't important.
As far as "But the Baltic is on the other side!" well, from the article screaming "the Russians are coming!"

"As the crisis over a 'mysterious' and unknown Russian submarine believed to be trapped in Swedish coastal waters escalates, President Vladimir Putin is taking no chances that their Northern European neighbor will use its military to threaten discovered oil fields Russia has made claim to in the Arctic region. And on Oct. 21, the Russian leader has decided to react with force and is deploying troops and robotic sentries to the Arctic to ensure the dispute reaches no further than its current location."
Russians, as the article states, put their military along the whole artic border. Well, good for them, it's their border. It won't cause WW3.
