The existence of this second hunt has been secret until now.
According to the newspaper, it started after a private person said to have long military experience on October 31 spotted what appeared to be a submarine conning tower in the waters between the island of Lidingö, and Nacka, on the southern shore of the waterway into the capital, and took a photo.
The image is said to have had much better quality than the well-publicized photo of a suspected object released to the public during the earlier hunt.
The head of information for the Swedish military, Philip Simon, has confirmed the story in Dagens Nyheter. But, he says, the second hunt was in vain, and the observation has been classified as a “possible submarine”.
In an interview with Swedish Radio News Saturday, Defence Minister Peter Hultqvist said the object searched for in the outer archipelago between October 17 and 24 was definitely a submarine.
He says he has seen positive evidence: “There is no doubt that there was a violation of inner Swedish waters. And that was why we made such a clear signal and report as far as we possibly could.”
