Footage from the Tuesday drill at the Tama Zoological Park shows some of the 100 participants, including zookeepers, police, and firefighters, tracking and chasing a man dressed in a full-body chimpanzee costume, Joinfo.com reports with reference to UPI.
The “chimp” used a tree branch to keep his would-be captors at bay while drill participants chased after him with nets.
The drill ended with a simulated shot from a tranquilizer gun putting the primate to sleep.
The zoo’s escape drills have become a yearly event, with previous simulations involving humans dressed as a zebra and a leopard.
