and with other divisions of Essex Police, such as the Drugs and Serious Crime Squad. FIOs are responsible for gathering intelligence on crimes committed in several areas or across area boundaries, so that patterns in these crimes can be analysed. Criminal Intelligence Analysts The role of the Criminal Intelligence Analyst is to use all the available information on criminal activity in Essex to assess trends which can be seen now and predict what might happen in the future.

Being portable, it enables the officer to travel to the victim's home or their hospital bed. They will interview the witness or victim using 'cognitive' interview which assists the witness to 'relive' rather than 'remember'. Having ascertained a general description of the offender this is then entered
