The abandoned vehicle where officers found the nitrous oxide canisters was also found to have had no registered keeper and to have been uninsured. The two shops on Derby Street were given closure orders for three months each. Officers say they applied for the closure orders after they received reports of anti-social behaviour surrounding the two shops from members of the public.
