2.8 The British Transport Police (BTP) is a national police force and has the task of policing the UK rail network, London Underground, Docklands Light Railway and some tram and metro systems. The BTP manages offending and anti-social behaviour on the railway network. It works in seven regional areas and has the ability to work across boundaries. It is part of the ViSOR community, working closely with police forces across England, Wales and Scotland.

2.9 The BTP should be involved in the risk management of MAPPA offenders where this is appropriate and necessary, including being invited to Level 2 and 3 MAPPA meetings. Invitation should be sent to the BTP Force Intelligence Bureau (email: fib@btp.pnn.police.uk telephone: 020 7830 8969 fax: 020 7830 8980). If unable to attend, the BTP should liaise with the owning police area and agree any tactical options for the management of the offender's travel, which the local police can put forward on its behalf.

2.10 The Royal Military Police is the military specialist for the Armed Forces in investigation and policing and is responsible for policing the military community worldwide. The Royal Military Police will act as a Single Point of Contact for all three services. They will be responsible for Category 1 offenders who are members of the Armed Forces and are deployed abroad. They will also work closely with colleagues in the local police force to ensure that any notification or other supervision requirements are fully met by MAPPA offenders deployed in the UK. Normal UK procedures apply to MAPPA offenders who are in the armed forces and who are deployed in the UK.

2.11 The local police force will usually be the conduit for any relevant information from the Royal Military Police to be fed into the MAPPA meeting for offenders in the UK. For offenders deployed abroad, the Royal Military Police will undertake an assessment of the potential risks an individual presents and ensure that all of the necessary arrangements are in place to manage them. The Royal Military Police is part of the ViSOR community and will ensure that the ViSOR record is kept up to date.

2.12 The Civil Nuclear Constabulary (CNC) provides protection for civil nuclear licensed sites and safeguards nuclear materials, nuclear site operators, policing and nuclear regulators, as well as interlinking with local police forces. There may be occasions when it is necessary to share information with CNC. The local police force will usually be the conduit for any relevant information from the CNC to be fed into the MAPPA meeting.
