Fredrik Kliman of the Ostergotland police said the tree was reported blocking a road near Borensberg and officers determined it was brought down by a beaver, The Local.se reported Friday.
"No one saw the tree fall, but we got a message about the delay and sent a patrol to check on the situation," Kliman told the TT news agency. "One of the policemen said that it was crystal clear that it was a beaver that chewed down the tree."
Kliman said public employees were called to clear away the tree and police decided not to pursue the culprit.
"We're not going to be hunting the beaver today, we have other things to do," he said.
