Around 200 visitors to Dublin Zoo were forced indoors this morning after an ape and its baby escaped.
The Siamang Gibbon called Sasak, which was carrying her baby Gizmo, swung off the island on which they are kept and onto the main complex.
A spokesperson for Dublin Zoo said strict escape procedures were followed.
All visitors were asked to stay in the restaurant while Sasak and Gizmo were contained.
In a statement Dublin Zoo said: 'At no time were the gibbons out of sight of zookeepers and the pair never left the perimeter of the zoo.
'The gibbons were never further than five metres from their habitat. The pair returned of their own accord within 30 minutes.
'The animals were never in any danger and of no threat to anyone else. They are both back in their habitat in the zoo unharmed and everything has returned to normal.'
