Operation Oak launched again for Aberdeen festive season
The annual crackdown on crime over the festive period in Aberdeen has been launched.
Operation Oak targets anti-social behaviour and violence with high-visibility and plain clothes patrols.
In 2011, offences throughout the Christmas and New Year period were said by police to be down by 66.5% after Operation Oak began.
Ch Supt Adrian Watson said: "We will not be complacent and we are determined to build on that progress."
