'World's saddest polar bear' kept in shopping centre prompts calls for a boycott

More than 150,000 people have signed an online petition calling for the closure of a shopping centre holding the "saddest polar bear in the world".

Animal rights activists say the polar bear in Grandview shopping centre in the Chinese city of Guangzhou is suffering so shoppers can simply take selfies with the animal.

The polar bear is believed to have to endure constant banging of the window of its glass enclosure, and videos shared online show shoppers gathering to take photographs of the animal.

The Animals Asia group called for the attraction to be shut down and urged the Chinese public not to attend.

Dave Neale, welfare director at Animals Asia, said there was "no excuse" for any animal to be "trapped", adding that it is widely believed polar bears are one of the hardest of all animals to effectively provide for in captivity.

The building houses two polar bears in total, six young belugas, five walrus calves, arctic foxes and a wolf.

Grandview promised to improve its facilities in April and announced plans to redesign the enclosure after meeting with Animals Asia to discuss the issue.
