A dead whale has washed up off the coast of Denmark, fueling speculation that it could be Timmy, a humpback whale rescued earlier this month in a £1.3million operation.

Timmy - whose health had severely deteriorated after being stranded near Germany since March - was released on May 2 after being transported in a water-filled barge by rescuers.

But just days after Timmy entered the North Sea off Denmark, and following a lack of tracking data, the German Oceanographic Museum determined he didn't survive the transition to deep water.

And now, the Danish Environmental Protection Agency has revealed that a whale, likely dead for some time, was spotted off the island of Anholt.

A warden with the agency told Danish TV that the whale is probably a humpback, and 10-15 metres long.
