Dubbed the 'British FBI' in the media, the National Crime Agency was set up in 2013 and has 4,200 officers across the country and in what it calls strategic locations across the world.

It tackles serious and organised crime and says organised crime is one of the gravest threats to national security - blighting communities, ruining lives and costing the UK well over £20 billion every year.

It also works in partnership with Crimestoppers as well as UK and overseas law enforcement to locate and arrest individuals who are wanted and believed to be overseas.
