Many of the Operation Nexus's successes have come as a result of posting UK Border Agency officers in 21 custody suites across London.
This now allows UKBA to run real-time immigration checks on individuals bought into custody suites for a crime and establish if they are wanted abroad, have previous convictions abroad or are here illegally.
Nexus also provides UKBA and police with additional tactics.
The sharing of intelligence now supports the removal of cases where previous charges have been dropped due to victims or witnesses refusing to cooperate with police due to intimidation or fear of retaliation.
