Two officers were a bit perplexed and skeptical about a report on Tuesday afternoon that there was a "monkey doing gymnastics on a guardrail" of the Autobahn near the Rheine-Nord exit in western Germany, according to a police report on Wednesday.
But when the officers arrived, they realized the report was completely true. They discovered the little capuchin monkeying about on a soundproofing wall on the roadway towards Amsterdam.
The officers called a nearby zoo to see if they were missing such an animal, but they were fully stocked. The officers then discovered that a family in the area had a license to own the furry creatures.
Despite their best efforts at luring it with chocolate, officers were unable to entice the monkey down from a tree it had hopped into.
In the end, they had no option but to call a licensed hunter who shot the creature with a tranquilizer dart.
Once the anesthesia had taken effect on the monkey they were able to retrieve him.
Police said it is still not clear how the monkey got onto the motorway.
