As people were walking in to a Minnesota zoo, three gorillas were walking out of their cages.
Jabir, Samson and Virgil, the three bachelor gorillas at Como Zoo, left their cages just before 10:00 am.
Their habitat door was left unlocked.
Staff immediately began their emergency procedures– keeping visitors indoors to be safe.
It took twenty minutes to secure two of the gorillas. But the third was found in a storage room playing with boomer balls.
Tranquilizers were on standby but were never used.
