Police say they are trawling through hours of CCTV footage in an effort to identify those responsible for disruption during the AugustBankHoliday demonstrations in Bradford.
The Creamfields Festival line-up has also been announced, with the Chemical Brothers headlining the event which takes place over the Augustbankholiday weekend at Daresbury, in Cheshire.
The AugustBankHoliday is always one of the busiest weekends on the roads in Devon and Cornwall, and road safety advisors say it is a time when motorcyclists tend to travel in greater numbers and some travel at excessive speed.
