The Waters gang are a criminal group of brothers. They became notorious for robbing English banks over a period of eighteen months around 2013 and 2014. There were at least three operatives in the group, including Brian and Derek Waters. At first the police, led by DCI Greg Lestrade, proved largely ineffectual while hunting the gang.
In one of the Waters gang's heist, they stole two million sterling from a Central London bank. The lack of evidence again perplexed forensic experts.
