An Austrian vet has criticised Justin Bieber for bringing a pet monkey on tour with him.

As previously reported, Bieber's pet primate was seized recently at Munich Airport because he didn't have the correct paperwork to bring him into Germany.

Speaking to the Sun, vet Kurt Grabenwoeger - who has been working with the monkey at the airport - believes that the idea of bringing the animal on tour is "monstrous". He said:

"These monkeys not only need to be with their mothers for at least a year, but they should also be surrounded by their family group. They are living creatures - not celebrity accessories like a handbag."

The vet continued: "He was snatched from his mother when he was around nine weeks old. That is much too early. He is clearly traumatised at being taken away from his family. We could not get him to eat until we gave him the cuddly toy he was clinging to when he was delivered to us. This obviously acts as a kind of surrogate parent. He keeps calling a lot for company - without his toy he won't eat at all."

It is said the monkey - which is named Mally - is only 14 weeks old and could be "scarred for life" as a result of the incident.
