SINGAPORE - In today's tight security climate, the airport is no place for monkey business.

However, it appears that one furry little creature did not get the message.

Several videos circulating on social media on Monday (Oct 29) showed a monkey roaming around the check-in area at Changi Airport Terminal 3's departure hall.

Videos of the monkey were uploaded to Facebook on Monday. In one clip, the monkey is seen on a high structure, making its way towards a leaf-covered wall in the terminal.

A spokesman for Changi Airport Group confirmed the Monday morning monkey sighting.

Changi Airport said it sought the assistance of the Animal Concerns Research and Education Society (Acres), which captured the monkey safely.

The airport spokesman added that there was no disruption to airport operations during the incident.

Acres deputy chief executive Kalai Vanan told The Straits Times that the monkey, which was identified as a long-tailed macaque, was rescued and relocated for its safety.

It was not being aggressive to the public, he added.

The macaque, which is native to Singapore, was captured with a dart, with assistance from the Agri-Food and Veterinary Authority of Singapore (AVA), he said.

Acres is assessing the health of the macaque and working with the National Parks Board to secure a release site within the next few days.

"As we urbanise more and our green spaces become more fragmented, sightings of lone macaques could potentially occur more," said Mr Kalai.

Members of the public are advised not to feed the macaques and to keep a distance from them, he added.

In a statement to The Straits Times, the AVA suggested that the public exercise caution when approached by monkeys, and to avoid making sudden movements or direct eye contact.
