Police ran vn number and gave me a call. Found a few miles from where it was stolen. No arrest for this bike, but an arrest for the other.
Someone reported someone shady to the police and it turned out that was my son's bike. Some new parts may be needed but with have the bike back by the end of the week.
The bike was recovered by Stolen Motorcycle Recovery London (https://stolenmotorcyclerecoverylondon.org, https://www.facebook.com/StolenMotorcycleRecoveryLondon/). I am just a guy that had his bike stolen and googled, I have no association with them ...
Notifyed by police, was found ditched and recovered. Was in a very bad condition.
