A search is continuing for for two monkeys who escaped from Belfast Zoo on Monday.

Six lion-tailed macaques managed to get out of their enclosure. Four of them have since been returned.

The other two animals, named Jade and Roxy, have been sighted onsite or in close proximity to the zoo.

A statement from the zoo says they pose no danger to the public, but experts are advising people not to approach or catch the animals.

The zoo team can be contacted on 00-44-28-9077-6277.

Lion-tailed macaques are strictly diurnal - so it is unlikely that any sightings will take place at night.
