Police have seized 18kg of "pure" cocaine with a street value of £2.5m at an address in Tooting.
Officers from Wandsworth Police's Tasking Team raided the property, the exact road name is currently unavailable, on Wednesday, July 26.
After a brief search of the building officers discovered wraps and bags hidden in the loft which contained 18kg of pure cocaine.
The information which led to the bust was secured after an earlier police raid at a separate address where £250,000 in cash was found.
Sergeant Steve Parker said: "This is a fantastic result and is a credit to my team for their hard work and tenacity around this investigation.
"This is a significant blow to criminals involved in drug trafficking and dealing on the streets of London."
It is not known at present if anyone has been arrested or charged in connection with the seizure.
