UPDATE: Good news in the case of the dog abandoned at a rail station. Kai has a new home, according to the Daily Record. The image of the sad mixed-breed dog captured hearts across the Internet. Her new owner was chosen from hundreds of applicants. Ian Russell, 52, said he's over the moon about adopting Kai and says it's like winning the lottery.

The Scottish SPCA posted a picture to its Facebook page of a dog found tied to railings at a railway station.

With the dog was a suitcase full of his belongings, which included a pillow, a toy, a food bowl and food.

Thanks to a microchip, they know the dog's name is Kai, but the original owner apparently sold the dog back in 2013.
