Synth Retention Bureau

The  is a special branch of the Commonwealth Police tasked with capturing escaped androids (or "synths").

Androids are usually used as slaves for the Institute, eventually, some androids learned enough to self-determine themselves and the world around them, so many have tried to escape the Institute. Since androids are state-of-the-art and are designed to resemble an actual human in as many ways as possible - even bleeding is simulated - they can be hard to track-down and capture, so the was created to specialize in capturing runaway androids. They have even made androids specifically to be operatives, as in the case of Harkness.
