Drug cops raided homes in Green Wrythe Lane, Carshalton, on Thursday December 11.
Officers from Sutton police forced their way into a home and arrested a 27-year-old woman as they executed the first of two drugs warrants. She was arrested on suspicion of possession with intent to supply cocaine and bailed until February, 2015, pending drug analysis work.
Officers were able to get into the second home without the use of force. A 47-year-old man was arrested on suspicion of money laundering and bailed until January 2015.
Two other people found in possession of marijuana received cannabis warnings.
Safer Neighbourhoods Inspector Neil Tyre said: "We want residents to get in touch if they suspect there are drugs related activities taking place in their street.
"Residents don't have to suffer in silence and we will act on their information to make local communities better and safer."
