A U-shaped object，resembling a silvery dome (穹顶), is now under inspection by Russian experts, after being secretly removed under cover of night from the possession of villagers who found it.

After discovering it on Sunday, locals from the village of Otradnesnky had managed to drag the “UFO fragment” from the thick forest where it had fallen. They loaded it onto a truck and took it through the snow to their village, where local inspectors then examined it before reporting Moscow authorities.

In an official statement, Sergey Bobrov, who found the object, agreed to keep it safe. But following their secret removal of the 200-kilogram metal fragment (碎片), police have it under close guard on orders from unnamed authorities.

The object has not had its origin confirmed yet. However, it does not come from a rocket or missile or be in any way associated with earth space technology, it has been announced. “The object found is not related to space technology. A final conclusion can be made after a detailed study of the object by experts,” said Roscosmos, the Russian space agency. Experts have also examined the object to determine whether it is dangerous. “We measured the radiation level near and inside the object. We found no radiation here,” said Yuri Bornyakov, who heads the rescue service department of the Kuybyshevsky district in the Novosibirsk region. Part of the fragment is made of ultra-strong titanium (钛), said Valery Vasiliev, the head of the Kuybyshevsky Department for Civil Defence and Emergency Situations.

A guess that it had come from a failed Kazakhstan rocket or satellite launch was also denied. “You can see inside it. All is open. It’s empty. No danger here. We were asked to take and store it. We brought it here. And now we are going to wait until they come to take it if they need it," said local police spokesman Sergei Sulein.
