The Dortmund Fire Brigade said firefighters responded to the Horde district of the city when a resident reported a squirrel stuck in a manhole cover.

"She covered the animal with a scarf so it could calm down and called the fire department for help," the post said. Firefighters removed the manhole cover and worked to extract the squirrel from the tiny opening. "But that turned out to be quite complicated, because the squirrel was not cooperative," firefighters wrote. "In the end, however, the firemen managed to free the animal. It was unharmed and disappeared straight onto the next tree."
