This is the shocking moment a grandfather in Indonesia was bitten by a rescued crocodile that locals believed was tame.

The unnamed pensioner and other tourists had visited the 'lucky' reptile that was saved from a flood last week and kept at a local theme park for devotees to make offerings.

Believing the crocodile was docile, the elderly man reached out to offer some food - only for the predator to viciously latch onto his arm and yank him into the water.

Footage shows terrified onlookers screaming as the beast thrashed the old man around in its jaws before letting go at the Cimory Dairyland centre.

Firefighters later arrived to take the elderly man to a hospital with a severely injured arm in South Sulawesi on Monday evening.

Onlooker Siti Aisyah said: 'The grandfather was bitten by a crocodile when he wanted to give him food. The residents immediately evacuated him and he was rushed to a hospital because his hand was badly injured.'

The local fire department chief Hasanuddin said the animal was caught in a flooded residential area on February 12 before being kept at the Cimory tourist attraction, which also includes mini-windmills, dairy animals and farming exhibitions.

Bosses had hoped that locals would visit in order to give donations to the croc. However, they have now let the animal be released by wildlife workers.
