Last night at about 11.15 we noticed 2 youths trying gates on Arthur Hind Close. As we spoke to the police on 999, they climbed into one garden, only to run off a minute or two later having presumably been disturbed. Unable to sleep, I looked out again at c. 11.45 and they were back. We rang the police again but they emerged from one of the gardens with a bike and headed off for Kedleston Rd. The police did arrive to check up around midnight.
They were extremely brazen - it wasn't very late, lots of houses overlook where they were, and the street lighting is excellent. They were about 5'10 in dark tarcksuits and hoodies, with covered faces.
BTW - CCTV would have been useless as you couldn't identify them at all in their "uniform".
