The Alliance for Animal Rights (AFAR) has said it is saddened to hear an orangutan tried to escape from its enclosure at Dublin Zoo earlier this week.
Maggie the ape went on the run for an hour on Wednesday after being kept in captivity for 24 years.
Zookeepers shot her with a tranquiliser before delivering her safely back to the compound.
The AFAR claims the animal was 'understandably frustrated'.
Dublin Zoo has rejected the criticism, describing its animals as healthy and active. It says escapes are very rare.
