I do believe that he left with intent not to come back to the train station for whatever reason. I also think he is not using a known network to get by, i think he is keeping a low profile, so he must be using the soup kitchens, food banks, homeless places to get by. So why not put up a couple of dozen missing posters in these type of places? I know there are loads in London but you can limit it from a radius of Bow. I also like the idea of a £1000 reward for his safe return. Some homeless person could earn some money for information. I would personally contribute to a fund like this. The find Dan Venes has just put up. £1000 for Dan returned safe. I think its a great idea.
