Officials in Germany are still pursuing Justin Bieber in an effort to settle a hefty bill relating to the pet monkey he abandoned earlier this year (13). The Baby hitmaker's capuchin, named Mally, was confiscated by customs guards in March (13) after he attempted to enter the country with the animal without the proper paperwork. Bieber was given until May (13) to reclaim the primate, but he failed to do so by the given deadline and Mally subsequently became the property of German zoo officials. The singer was sent a bill, reportedly amounting to almost $11,000 (£7,330), to cover the cost and penalties of housing the monkey during its detention period, but authorities have yet to receive anything from the pop superstar, despite sending him another copy of the invoice on Wednesday (13Nov13). Ellen Frederichs, attorney for Germany's Federal Agency for Nature Conservation, tells Celebuzz.com, "As Mr. Bieber should be informed about his payment obligations by now, we hope that he takes his responsibility and settles the costs he has caused to the public, just like anybody else would have to do." If Bieber, who reportedly bought a new pet monkey to replace Mally upon his return to the U.S., continues to ignore the bill, authorities could take him to task the next time he lands in the country. The singer has been busy stirring up trouble across the globe - he has also fallen foul of police in Brazil, where he has been hit with a vandalism charge, after spraying graffiti on an abandoned hotel in Rio de Janiero earlier this month (Nov13).
