"There was also evidence that both addresses were being used for 'chemsex' parties," police said. "Following this, further searches were carried out ... where Bleta and another man were arrested in possession of larger quantities of the Class A drugs."
James Shugg.
Shugg, Bleta and Montes-Bailon were sentenced at the Southwark crown court on Monday to five years, four years and two years respectively for conspiracy to supply class A and class B drugs.
"Telephone and text evidence and indeed evidence of moneys going between accounts suggest that the conspirators had been active for a considerable period before those dates," Judge Joanna Korner was reported in The Standard as saying.
"Our team has broken up a network where drugs were being made available to vulnerable users," DS Vince Abrahart of Westminster Crime Squad said. "During the investigation it was shown that the effects of the mixtures of these drugs used at 'chemsex' parties can prove fatal. The reckless supply of these drugs had to be stemmed.
"The sentences handed down to those involved show that the dealers of these dangerous substances will be brought to justice and made to pay for their criminal actions.
"Shugg, Bleta and Montes-Bailon formed a supply network to distribute wholesale quantities of drugs to a large client base they built up through social media and word of mouth referrals. As a result of these arrests and charges, significant quantities of Class A and B drugs have been seized and this criminal network has been broken up."
Shugg left the bank in mid-2015. A Westpac spokesman said: "We don't comment on former employees."
