The 17 meter long privately own submarine Nautilus UC3 sank in Koge Bay near Copenhagen, Denmark. The sub had suffered a technical fault with a ballast tank valve causing the submarine to sink in less than a minute. The vessel’s owner, Peter Madsen, was the sole person on board at the time of the incident. He was able to escape and jump into the sea before the submarine plunged for the bottom. Danish authorities were alerted when the submarine failed to arrive. Multiple rescues vessels were deployed in a search and rescue operation. Luckily, he was spotted and safely rescued. He was later taken to Dragor Harbor. No reports of injuries.

August 12 Update

Authorities arrested Peter Madsen under the suspicion of murder. Reports state a journalist was on board the submarine at the time when it sank. Madsen stated he had dropped off the reporter on an island three hours into the voyage.  However, authorities were unable to locate her after she was reported missing. Indications point to the submarine being intentionally sunk rather than by a stuck ballast tank valve as initially reported.
