A 20-year-old woman who admitted supplying “vulnerable people” with Class A drugs at ‘Chemsex’ parties has been jailed for four years.

Sara Bleta, of Union Court in Richmond, was sentenced to four years' imprisonment for conspiracy to supply Class A drugs.

She was also jailed for nine months for conspiracy to supply Class B drugs, but it will run concurrently with the longer sentence.

Bleta’s associates, 53-year-old James Shugg and 26-year-old Alejandro Montes-Bailon – both from Camden – were jailed for five years and two years, respectively.

The three were sentenced yesterday (March 20) at Southwark Crown Court after pleading guilty to the offences at an earlier hearing.

A number of reported illnesses and injuries in Soho and the West End were linked by police to crystal meth, mephedrone, GHB, LSD and cocaine, prompting an investigation into the trio.

Two addresses in Camden were raided in August 2015, where Shugg and Montes-Bailon were arrested along with another man, Lee Cash.

There was also evidence that both addresses were being used for 'Chemsex' parties, Metropolitan Police said.

‘Chemsex’ parties, sometimes known as ‘party and play’, refer to gatherings where users engage in sexual activities under the influence of drugs within groups.

Another search was done in Camden, and Bleta and another man, Thomas Larkin, were arrested in possession of larger quantities of the Class A drugs.

Those arrests led officers to an address in Chelsea, where they found two other men in possession of smaller quantities of crystal meth and GHB. Both men were arrested.

Detective Sergeant Vince Abrahart said: "Our team has broken up a supply network where drugs were being made available to vulnerable users.

"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."

Lee Cash, 53, was sentenced in May 2016 after pleading guilty to possession of Class A drugs, receiving a 12 month conditional discharge, and was ordered to pay a victim surcharge.

Thomas Larkin, 31, from Feltham, was sentenced on March 13 to 300 hours' community service after pleading guilty to being concerned in the supply of controlled drugs.
