“The stranded humpback whale near Anholt is the same whale that was previously stranded in Germany and was the subject of rescue attempts,” Jane Hansen, head of division at the Danish Environmental Protection Agency, told CNN on Saturday.

The agency confirmed the whale’s identity after one of its workers found and retrieved the faulty tracking device that had been attached to him during his rescue attempt.

“The position and appearance of the device confirm that this is the same whale that had previously been observed and handled in German waters,” Hansen said.

Timmy was found on Friday near the island of Anholt – situated in the Kattegat Strait between Denmark and Sweden, about 130 kilometres from where he was released.

He was first spotted at the beginning of March in Wismar harbor, entangled in a fishing net, and had to be freed by emergency services.

Then, he became stranded at the end of March when he got lost in shallow water near Timmendorfer Strand, a town on Germany’s north coast that gave him his nickname.

That prompted an extensive rescue effort, and widespread media coverage as the whale’s ordeal was livestreamed around the world.

But rescuers could not free the whale, and as his health declined, they stopped their efforts.

However, another privately funded rescue attempt, which directed Timmy to swim into a barge before shipping him out into the open sea, pressed ahead despite warnings from scientists that the whale was too weak to survive.

During the time he was stranded, he spent days barely moving, breathing irregularly and suffering from a bad skin condition caused by the Baltic Sea’s low salt content.

Such warnings meant the rescue became mired in controversy.

To its critics, it represented a form of animal cruelty, causing the whale severe stress for no reason.

“I believe the whale will die very soon now,” Thilo Maack, a marine biologist for Greenpeace, told the Associated Press in April as rescuers tried to set Timmy free.

“And I would also like to raise the question: What is actually so bad about that? … Yes, animals live, animals die. This animal is really, really very, very, very sick. And it has decided to seek rest.”

But to others, like the province’s environment minister, Till Backhaus, who allowed the private rescue attempt to go ahead, it was a normal response “to use even the smallest chance when a life is at stake,” as he told AP.

There are no plans to remove Timmy’s carcass, the Danish Environmental Protection Agency added, since it “is not currently considered to pose a problem in the area.”

It urged people to keep a safe distance and not approach the whale for health reasons – and in case it explodes.
