Two people have been charged after drugs worth more than $800,000 were seized from properties in Melbourne's inner southeast.
Detectives searched the homes in Southbank, South Yarra, Balaclava and Richmond on Thursday, finding about 2.6 kilograms of ketamine and 400 grams of cocaine.
The drugs have an estimated street value of $840,000.
A small quantity of cannabis, steroids and prescription medication were also seized, along with almost $90,000 cash.
Police on Friday charged a 33-year-old Balaclava man with trafficking a large commercial quantity of ketamine and cocaine.
A 32-year-old man from South Yarra faces two counts of possessing a prohibited drug.
Two others - a 33-year-old South Yarra woman and a 46-year-old Southbank man - were arrested but released without charge.
Detectives believe the drug seizure is connected to another in Lara last month, where federal police found more than 200kg of ketamine.
