abandoned speed triple 955i

a couple of days ago we passed by a dude pushing his bike on north circular between woodgreen and southgate. we stopped to help him and ask what happened, by the way his gear looked he just had an accident. somebody hit him from behind ( broke his number plates) and pushed him into another vehicle or something. we asked him if he’s ok , he barely said anything and took off leaving the bike with the handlebars locked on the side of the road. we thought he’s going to call for help or something and we stayed there to wait for him to return. he never did …instead some other dude stopped to collect the bike in a ford connect white van-i’ve memorised his plates.he asked about the rider and i told him in which direction he went. after that he too went off…said he will return for the bike later.
THE BIKE IS STILL THERE, AFTER 2 DAYS…
