Twenty five years after he got lost whilst traveling on a train in India, a man found his mother using the unlikeliest of technology, satellite images.
Here's the incredible story of how Saroo Brierly used Google Earth to reunite with his long lost mother:
Saroo was only five years old when he got lost. He was travelling with his older brother, working as a sweeper on India's trains. "It was late at night. We got off the train, and I was so tired that I just took a seat at a train station, and I ended up falling asleep."
That fateful nap would determine the rest of his life. "I thought my brother would come back and wake me up but when I awoke he was nowhere to be seen. I saw a train in front of me and thought he must be on that train. So I decided to get on it and hoped that I would meet my brother."
Saroo did not meet his brother on the train. Instead, he fell asleep and had a shock when he woke up 14 hours later. Though he did not realise it at first, he had arrived in Calcutta, India's third biggest city and notorious for its slums. [...]
Soon he was sleeping rough. "It was a very scary place to be. I don't think any mother or father would like to have their five year old wandering alone in the slums and trains stations of Calcutta."
