Guernsey Border Agency
The Guernsey Border Agency is the law enforcement body charged with tackling cross border crime and administering the customs and immigration systems for the Bailiwick of Guernsey. The agency is headed by a Chief Officer - Patrick Rice (Head of Law Enforcement) 

The Agency has been established in shadow form following a decision to separate the executive functions of setting strategy and policy (which will be the responsibility of the Home Department and a law enforcement commission) and operational law enforcement. The island has had an integrated customs and immigration function since 1975. The new agency brings financial crime and drugs responsibilities to the new agency from the Guernsey Police. The agency has around 90 officers and staff. It has a cutter and can call on mutual aid from French customs and UK Border Force aircraft and vessels if required. The agency is based at New Jetty, White Rock, St Peter Port, Guernsey. Officers
