June 29 (UPI) -- A red ruffed lemur escaped from an Amsterdam zoo and crossed several roads and tram tracks before take shelter in a tree.

The lemur escaped Friday afternoon from the Artis Zoo and was spotted about an hour and a half later in a tree along a road a few blocks away.

Officials said the lemur would have had to cross several streets, including one with tram tracks. The animal was reportedly almost struck by a taxi.

"That must have been incredibly stressful," zoo official Maartje de Vries told Het Parool.

The lemur was on a branch about 20 feet over the ground. Officials made the decision to dart the animal with a tranquilizer before attempting to bring it down.
