We think this looks wrong http://www.ukcrimestats.com/Police_Force/Metropolitan_Police – October 2013 ASB incidents were 4 times lower than each month either side of it. The official data we download from http://data.police.uk/data/ has not changed and shows 5,151 incidents in October 2013 but 22,186 in November 2013 and 22,,476 in September 2013. Missing 15,000 really is a lot if that is what has happened. The total combined ASB and crime total would normally be around 80k so percentagewise, this means a lot.
I have informed the Home Office and will keep you posted here on their reply.
