Kingston (South London News) May 22, 2026.As reported by the Metropolitan Police, Dawid Gasiewski, 32, from Kingston, received a sentence of 14 years and four months after being convicted as part of the organised crime group’s activities. The force said the network was responsible for bringing more than 300kg of cocaine and more than 60kg of heroin into the UK, with a total estimated wholesale value of almost £8 million.
The Met said the other defendants were also sentenced in connection with the same operation. Andrzej Walas, 48, of Hubert Road, Slough, was given 26 years in prison, while Robert Francuz, 43, of Heath Park, Hemel Hempstead, received 21 years.
Jamie Allen, 29, of Birmingham, was sentenced to 13 years, and Jagjit Singh, 30, also of Birmingham, received 10 years and six months. The five sentencing decisions were handed down at Kingston Crown Court on May 21, according to the police statement.
What did police say about the drugs conspiracy?
Detective Constable Leon Ure, of Specialist Crime South, said the case involved a criminal venture carried out on a “gigantic commercial scale”. He added that it would have likely caused violence and destruction on local streets.
The police description places the case within the wider pattern of organised drug supply networks operating across London and beyond, where imported Class A drugs are moved in bulk before being broken down for distribution.
The scale of the seizure and the sentences imposed suggest the court treated the offending as highly serious, reflecting both the quantity of drugs and the risk linked to organised crime.
Who were the defendants sentenced?
The Metropolitan Police identified the five men sentenced as part of the same investigation. Their sentences were as follows:
- Dawid Gasiewski, 32, Kingston: 14 years and four months.
- Andrzej Walas, 48, Hubert Road, Slough: 26 years.
- Robert Francuz, 43, Heath Park, Hemel Hempstead: 21 years.
- Jamie Allen, 29, Birmingham: 13 years.
- Jagjit Singh, 30, Birmingham: 10 years and six months.
Police did not set out in the quoted material the full legal steps that led to each sentence, but the statement makes clear that all five men were dealt with at the same court hearing. The case was presented by the Met as one involving organised criminal activity at a major commercial level, rather than a small-scale or isolated operation.
Why does this case matter locally?
The case is significant for Kingston because one of the men jailed was from the borough, and the court proceedings took place at Kingston Crown Court.
The sentencing also underlines the role local courts play in dealing with large drug importation cases that affect communities far beyond the immediate area.
Drug importation cases of this kind often attract attention because they can feed wider supply networks and increase the risk of associated crime, including violence, exploitation and street-level dealing.
In this case, police explicitly linked the scale of the operation to likely harm on the streets, reinforcing the seriousness of the investigation.

Background of the development
This case sits within the broader work of Specialist Crime South and the Metropolitan Police’s efforts to target organised crime groups involved in the importation of Class A drugs.
The force said the network dealt with more than 300kg of cocaine and more than 60kg of heroin, which indicates a highly organised supply chain rather than a one-off offence.
The sentencing on May 21 followed the police investigation and court process that brought the men before Kingston Crown Court. The Met’s comments suggest officers viewed the operation as one designed to move substantial quantities of drugs through commercial channels for distribution in the UK.
Prediction
For Kingston residents and communities across south-west London, the case is likely to be seen as a clear example of how organised drug supply can reach local areas even when the operation itself is spread across multiple towns and cities. It may also increase public attention on police activity against county lines and wider organised crime networks, particularly where local people are drawn into serious offending.
The sentencing may also act as a warning to others involved in similar conspiracies, as the court imposed long custodial terms on all five defendants. For the wider audience, the main effect is likely to be reassurance that major drug importation cases are being pursued aggressively, while also highlighting the scale of harm such networks can cause.
