Laboratory Monkeys Escape From Truck in the U.S.

Laboratory monkeys have escaped in Pennsylvania, USA. The animals were being transported by truck when the vehicle was involved in an accident, causing four monkeys to flee.

One of the monkeys has been found sitting in a tree. They managed to bring the monkey down using a tranquilizer, while the other three are still hiding. Scientists have expressed concern that they may freeze, as temperatures around Denver are expected to drop to -15 degrees Celsius at night.
