A total of 29 arrests were made in 24 hours. The raids were the latest phase of a police crackdown on the so-called GAS gang - which is based in Lambeth - that has seen a total of 88 arrests.
It's a London-based gang but they're extending their drugs network and finding new markets to ensure they get more money.
They've got their tentacles into Home Counties and further afield because they want to expand the amount of profit they can get.
The reason we target them is that we still get the associated violence in London when they return.
