Justin Bieber bought an endangered baby monkey illegally on the black market - then neglected it so badly it required intensive care, a zookeeper claimed today.

The 20-year-old star, who has also been accused this week of dumping his pet puppy, came under furious attack from the 'surrogate mum' who has adopted abandoned capuchin monkey Mally.

'Monkey mum' Jenny Niawoehner told MailOnline: 'I would not like to meet Justin Bieber because I would not have pleasant things to say to him.

'Mally was frightened [when he arrived], he was alone, he was disoriented and we did not know how things would work out for him. He needed to be cared for constantly.'

The cheeky capuchin was confiscated from Bieber when he flew into the country for a concert last year because he had failed to obtain the right paperwork. He never returned to collect him.

'Showing off': Justin Bieber posted pictures of himself with his monkey Mally but never bothered to send on paperwork showing ownership or get a certificate to allow him to travel. Now Mally has a new owner

So close: After Mally the capuchin was dumped by Bieber, zoo assistant Jenny Niawoehner had to spend hours rocking and nursing him because he was so traumatised by the experience with Bieber

Staff at the Hodenhagen Serengeti Wildlife Park in northern Germany that Mally now calls home believe it was probably bought illegally on the black market, because promised paperwork from Bieber's management showing that he was lawfully acquired never showed up.

'It simply never arrived, despite several promises,' said a spokeswoman for zoo. 'We can only assume the monkey was not acquired legally. We have never heard from, or seen, Justin Bieber ever since and we do not expect to.

'Mally is now the property of the Federal German government and is happy here.'

The blistering attack came after Bieber was also revealed to have dumped his pet puppy, Karma.

The American bulldog pup was bought on a trip to Canada last Christmas as a present to himself but never collected from a trainer, who posted on Facebook: 'Karma will bit you in your ass, Biebers.'

It is the third pet that the multi-millionaire pop prodigy has discarded - including a hamster - and triggered claims the pop star is guilty of animal cruelty.

The smuggling of the bright, cheery capuchin monkey has intensified in recent years and the fact that Bieber jetted into Germany with one on his arm in March last year only served to increase their popularity - and their suffering.

'I would not like to meet Justin Bieber because I would not have pleasant things to say to him,' said Jenny, 31, who brought Mally up when he was brought to the park not far from the city of Hanover at the end of May last year.

'He was frightened, he was alone, he was disoriented and we did not know how things would work out for him,' she added.

'Mally needed to be cared for constantly and from the way he reacted here, I believe that Justin Bieber probably only ever interacted with him when he wanted to have his picture taken with a fan. I am sure that for the rest of the time he was passed around his entourage when he needed constant contact with a parent figure.

'From the way he behaved, I could see that was not the case. These are clever, sensitive creatures. He would probably recognise Bieber if he ever came to visit him. But what he would think of him.......' Jenny, who spent endless hours hugging and feeding the tiny Mally, who was just months old when he was acquired by Bieber, does not finish the sentence. What she thinks about him is evident.

Growing up: Mally had to be nursed constantly when he was adopted by Hodenhagen Serengeti Wildlife Park after being abandoned by Bieber at German customs but is now making progress

At risk: Although capuchins are tiny and cute, they are not pets and Mally's new owners say he was bought from the black market, where monkeys fetch between $6,000 and $20,000

Neglected: Mally was neglected by Bieber to such an extent that he needed to learn new behaviours when he was confiscated by German authorities last year, according to his 'new mum' Jenny Niawoehner

Irresponsible: Justin Bieber tweeted pictures of himself 'Kickin it' with his monkey but failed to obtain a certificate to bring it into Germany then abandoned it at customs

'It makes me mad to think he can be a role model for young girls,' she went on.

'They come here in the summer, see Mally, and say, aahhh, I want one. But these are not pets. They are wild animals and living things in their own right who are not playthings. He should never had had Mally. We are just lucky he was not so disoriented that he could not learn from, and be accepted by, the monkey group he now lives with.'

Mally hit the headlines on March 28 when Bieber, 19, was on a world tour and landed at Munich airport without any vaccination certificate for Mally and no permission to import a live animal from outside the EU.

Bieber played on, but Mally was sent to an animal shelter. A statement from the shelter said the monkey should not have been kept as a pet and was too young to have been taken away from its mother.

Experts say capuchin monkeys should be kept in groups as they are sociable animals.

Bieber was given several weeks to produce the health papers required to get him back, but failed to do so. He has never sent any money to the Hodenhagen site - not that they want it - nor has he or anyone in his management ever enquired after Mally's health. But Mail Online was granted a rare visit to see him and can report that he doesn't miss the jet-set lifestyle of the rich and famous one bit.

'He is very happy here,' said Jenny, who dyed her hair a shocking punk-pink only days ago - much to the consternation of Mally. 'He has very special facial expressions and he was most perplexed when he first set eyes on me after the dye job!

'He was wary at first, then came and pulled at it, sniffed it, sniffed me to make sure it was me underneath it. He is a happy boy most of the time but he has his moods like anyone else. It is too cold outside for him now so he will be inside with the group for the rest of the winter.

Christmas treat: Although Mally was neglected when he arrived at the Serengeti Park in Hodenhagen, northern Germany, he is now thriving on a diet of vegetables and fruit and is getting a melon tart for Christmas

Endangered monkey hunted to sell as pets for $20,000 The critically endangered Margarita capuchin monkey - Cebus apella margaritae - is a sub-species endemic to Isla de Margarita in the Venezuelan Caribbean Sea, and is the only wild primate on the island. Its numbers have been drastically reduced in recent years by poachers who sell them for pets. There are only a few hundred left in the wild but they are still hunted. The biggest fear is of pets escaping back into the jungle, bringing with them potentially lethal diseases they have picked up from humans, and devastating the remaining wild colonies. The blonde capuchin and the yellow breasted Capuchin of Peru and Brazil are both under threat. Some 100 of both are estimated to have been poached by pet traders in the last year and, as there are less than 200 blonde Capuchins in the wild, these are on the brink of extinction. Hunters get around $1,000 US dollars for a monkey like Mally, but can command up to $5,000 dollars each for a rare example like the blonde. Unscrupulous dealers in America and Europe sell on capuchins for anywhere between $6,000 and $20,000, sometimes more. There are an estimated 100,000 Capuchins as pets in the USA alone, according to the ASPCA in New York. While poaching is a major problem, animal rights groups say it is the inhumane breeding of the monkeys that concerns them more. Advertisement

'He exists on a diet of vegetables and fruit. He particularly likes melon because he likes to pick out the seeds and chew on them. At Christmas he will be getting a special fruit tart as a treat.

'His adoptive mother Molly took to him right away but there were no guarantees when he arrived, friendless, nervous, alone and timid.

'But now he is chirpy and friendly all the time. I used to spend hours nursing in him in my arms but he's not allowed to come to me now in that way because we need to wean him off human contact. I still tickle and scratch him though, but he was a bit grumpy last week because his front tooth was coming through.'

If, as seems likely, Mally was acquired illegally, he helped to fuel a barbaric, multi-million pound trade in south American countries like Brazil, Peru and Chile where their mothers are often slaughtered so their young can be captured for selling on. Within weeks of birth they have the intelligence of a six year old human child - and its feelings and needs.

'People who think they make cute pets are completely wrong,' said Jenny. 'They need the love and care of their parents and the family group. Luckily we were able to give that to Mally. Capuchin monkeys live until they are 50 or 55 so it looks like he and me will become pensioners together!'

In many South American countries, the illegal trading in Capuchin monkeys is second only to the narcotics business.

Captured, distressed, malnourished and psychotic because of their treatment before they are passed on, these monkey-cousins of man often die in transit to pet traders - some legal, most not - around the globe because of their treatment.

A common sign of stress among capuchins is a hairless tail: the monkeys pull out all the fur from it when they are stressed.

Endangered: Illegal wildlife trafficking of capuchin monkeys is thriving in South America and the safari park where Mally is now living believe he was bought on the black market

Even in countries where breeding Capuchin monkeys is legal, the trade is equally gruesome. Debbie Leahy, manager of captive wildlife protection for the Humane Society of the United States, said: 'Breeders will pull newborn monkeys from their moms when the baby is just a few days old. So then the animals are bottle-fed and hand-reared by people. They never learn to become a capuchin; they don't have the opportunity to learn appropriate behavior from their mother and others in their group.'

A lot of monkeys become more aggressive the older they get. And a lot of monkey owners go to a vet and demand for their teeth to be removed.

'Sometimes they do a full dental extraction because the animals bite,' added Ms. Leahy.

'People want to emulate celebrities they admire. When somebody like Justin Bieber is irresponsible and goes out and gets a pet monkey, he sets a very bad example. You can admire an animal without wanting to cage him and keep him in inhumane conditions.'

In 1972 the Duke of Bedford had the idea of building the largest safari park in Europe with business partners from America. In 1974 this plan was realised and, since then, the Sepe family has run the park. When it opened the investors had spent about seven million pounds but in 1983 the park was extensively renovated at a cost of several million more.
