for cross-matching missing persons with unidentified persons or bodies, as well as maintaining an index of dental records of missing persons and unidentified bodies. The MPB also manages a missing persons and Child Rescue Alert website, and analyses data to identify trends and patterns in disappearances. UK Human Trafficking Centre National Injuries Database The National Injuries Database also transferred from the NPIA. It provides additional support to police forces by providing analysis of weapons and wounds, and seeking to identify similarities to aid investigators in determining which weapon may have been used. The database holds over 4,000 cases of suspicious deaths, murders and clinical cases, and contains over 20,000 images. Central Bureau Chemical Suspicious Activity Reports UK Financial Intelligence Unit SOCA via the UK Financial Intelligence Unit took over responsibility for dealing with suspicious activity reports (SARs), previously made to the National Criminal Intelligence Service (NCIS) under the money laundering legislation. This function is now part of NCA. NCIS received just under 200,000 SARs in 2005 and throughout its life was heavily critical of the banking and financial services sector, and the Financial Services Authority, for not being more transparent or forthcoming in reporting their customers' suspicious activity. Despite criticism from professional representative bodies that the disclosure rules are too broad, SOCA said that up to one in three SARs lead to or add substantially to terrorism investigations; that HMRC estimates that around one in five SARs identifies new subjects of interest, and one in four SARs lead to direct tax enquiries; and many arrests and confiscations of criminal assets. Serious Crime Analysis Section The Serious Crime Analysis Section moved to SOCA from the National Policing Improvement Agency on 1 April 2012 in advance of the planned establishment of the National Crime Agency in 2013. SCAS is based at Foxley Hall in the grounds of the Police Staff College, Bramshill in Hampshire. It was originally formed by the Home Office in 1998 to identify the potential emergence of serial killers and serial rapists at the earliest stage of their offending. This scope has since broadened to include the analysis by specialist staff of rapes, serious sexual assaults and motiveless or sexually motivated murders. Criminal case files are received by SCAS from all police forces in the UK at an early stage in the investigations. The information is coded and placed on a single database, ViCLAS (Violent Crime Linkage Analysis System).
