Your thoughts on the 4K year old statue in the UK that keeps turning around?

There’s a museum in the UK that houses many statues. One that is 4K years old has suddenly, after almost 100 years in the museum, begun turning all the way around over 24 hours. Only one man has the key to the glass case and says it began doing this recently. It turns in place; that is, it doesn’t move forward or backward. So, they cleverly installed a time lapse camera which is recording it turning around. The statues next to it don’t move. I think the museum is in Manchester if you want to google it.
