Los Angeles, May 18 (IANS): Pop sensation Justin Bieber will have to pay hefty bills to the quarantine centre caring for his pet monkey Mally.

Bieber has been asked to shell out thousands of pounds for care, food and vet visits to Mally, the capuchin, who he sneaked into Europe on a private jet.

The 19-year-old's pet was seized by German customs March 28 when the singer failed to produce the necessary paperwork for it.

Bieber had insisted his exotic pet accompany him on a transatlantic flight to Munich while on tour, breaking Germany’s strict health laws. His management company told the shelter to dump 20-week-old Mally at a local zoo, according to the Munich Animal Protection Centre.

But customs are yet yet to receive a formal request to do so, either from Bieber or an authorised representative.

Mally is thought to have been given to the singer to mark his 19th birthday by music producer Jamal Rashid.

As of now, the abandoned monkey's only companions in his room at the shelter are his carer Conrad Dressler, 29, and an old teddy that Bieber gave him to play with.

The monkey could be in danger, said centre spokesman Judith Brettmeister.

“Mally is lonely. He could suffer serious psychological problems if he doesn’t start living with other capuchin monkeys soon,” he said.
