A humpback whale was in the Baltic Sea. People call the whale Fridolin or Timmy. A private group saved the whale. They moved him to the North Sea by boat. The whale was free on Saturday.
The whale wears a GPS tracker. The device shows the position of the whale. But the device sends no data now. The group says: The device sends signs of life. Experts do not believe this.
Experts say: Normal trackers cannot measure signs of life. This needs special tools. The group did not check the device. Experts think this is bad. They call this work careless.
Maybe the whale is sick or weak. He was often stuck on the beach. Without data nobody knows if he lives. Some experts say: The chance to survive is small.
