The raids took place at addresses in the suburbs of Solna and Tyesö and the suspects were remanded in custody on Wednesday.
The bust was the largest by the Stockholm police in quite some time.
“In recent years the biggest seizure has been around 50 to 50 kilos. If you compare with that, this is really big,” said Bo Eliasson of the Stockholm police to the Dagens Nyheter (DN) newspaper.
The raids came after several weeks of surveillance in Solna and Tyresö following the arrest in November of a man in connection with the seizure of 10 kilogrammes of cannabis.
According to a statement on their website, police believe one of the suspects arrested at the weekend is responsible for supplying the drug taken in the November arrest.
Police estimate the cannabis confiscated during the weekend raids has a street value between 9 and 15 million kronor ($1.1 to 1.8 million).

While the investigation is in its early stages, police expect to involve both Europol and Interpol as the suspects have ties to other countries.
