Horrific footage shows how baby elephants are 'broken' at cruel training camps before they are set to work in the tourist industry in Thailand.

Staff recorded the calves being abused so they can be taught to paint, spin hoops, carry passengers and stand on their hind legs for the entertainment of holidaymakers.

In the video which was passed to an animal welfare group, the mother named Gintaala and her 16-month-old baby Boonshoo are seen being trained with disturbingly barbaric methods.

The baby elephant is tied together with its mother as they feed on grass until the mahouts force them to separate.

Off-camera, the mother elephant resisted when the mahouts took away her baby, while Boonshoo was recorded crying in distress after being separated with the adult.

Animal rights group World Animal Protection, which compiled the dossier of footage to highlight the cruelty, said the baby elephant's ''instinct was then destroyed'.

When Boonshoo was deemed ready to learn tricks, she was chained up alone in a sickening chamber made from four huge posts. The baby was then taught how to follow commands from the sticks and ropes.

The jumbo's natural instincts were ''replaced by the pain and fear of the hook'' and being chained in the posts forced it to become used to ''loud noises and stress''.

Painful punishments can be seen being inflicted on the baby elephant, with mahouts striking it with a bullhook or paddle with nails.

Another scene in the compilation of abuse shows a baby elephant's legs collapsing while walking with the workers under the sun, but it was threatened and hit so it stood up.

The poor creature can be heard letting out a loud groan after standing up to walk again.

The video compilation was recorded by undercover staff using hidden cameras in 2019 before it was handed to animal welfare groups earlier this year.

It was recently released by World Animal Protection, a nonprofit organisation, which campaigns to end animal abuse.

WAP Thailand's Wildlife Campaign Manager Chat Narong Muangwong said they are working to educate tourists to stop visiting elephant shows, as demand from tourism is the main driver of the abuse.

She said: "As of January 2020, we have 2,798 elephants in the tourism industry, a 70 per cent increase over 10 years ago.

"With such a large and ever-growing population of elephants, the welfare risks will increase accordingly. Especially when tourism is disrupted by the COVID-19 crisis."

WAP Thailand's Public Engagement Manager, Joe Aphiluck, added: ''The video of the elephants were all recorded in Thailand. We can't reveal the exact locations as it would not be safe for the people involved with the investigation.

''There is still a lot of work to do to end the abuse of elephants.

''Tourist demand is a key driver of these atrocities, while the complexity and lack of modernity of the many Thai elephant laws make the safeguarding of elephants' welfare more difficult.''

However, the animal rights activist said that tourists are becoming more aware of the issue and choose to see animals in their natural habitats rather than facilities with cages.

World Animal Protection said their researchers assessed almost 3,000 elephants in 2017 and found that more than three-quarters of these animals live "severely cruel" conditions.
