The roof blew off their enclosure.

Dublin Zoo has confirmed that a daring group of monkeys escaped from their enclosure as Storm Ophelia was battering the country last October.

The three Sulawesi crested macaques staged the break-out while the zoo was closed due to the bad weather.

A report into the incident reveals that the monkeys made a 20 foot jump onto an overhanging electric fence after the roof was blown off their enclosure.

The fugitives were eventually located in a nearby tree and were safely returned home.

In a statement this afternoon, the zoo said the “incident was dealt with swiftly effectively and no animal was harmed.”

It said a later ‘incident debrief’ found that the response from the animal care team was “robust and effective” while the zoo as a whole was found to have displayed an “excellent response time and communication between the animal care and security team.”

Since the incident, the zoo has made a number of alterations to the monkey’s island habitat - with the climbing frame lowered and the electrical fence raised.

The zoo has moved to reassure customers that it views visitor safety as paramount and insisted that all of its habitats either meet or exceed safety requirements.
