There were 558 cases of wilful fire-raising recorded in the city in 2011-12, down from 769 in 2006-2007 and 634 in 2010-11.

Fire-raising figures have now fallen as quickly as those for vandalism, which are 40% lower than in 2006.
Superintendent Graham Clarke, from Strathclyde Police's Safer Communities team, said: "We are encouraged by the reduction in the number of fires being started deliberately. However, we are not complacent, and will continue to work to drive down further those figures."
