Again night skaters riders causing chaos on London streets. Rollerbladers blocking the other motorists from driving is just illegal. Only Police can stop other vehicles, NOT so called marshals..
Mob is called LFNS (London Friday Night Skate). They are not regulated, they do whatever they like.
One of the skaters faked an accident, like we was ran over. All was registered on dash cam. This is why you need one just in case to avoid any unnecessary trouble with Police or prevent insurance scam.
