Good afternoon.  Over the past couple of days there have been numerous reports of youths on off road motorcycles on the riverbank, the footpaths surrounding the ponds and Northfield in Barlby.  I have been on foot patrol and mobile patrol today to prevent this from recurring and I am working from 1500hrs - midnight over the next 3 days where I will continue my patrols.  In the meantime, please report any incidents of this nature by calling in 101 or if there is a danger to life or a crime is in progress, 999.
