(North London News)  April 3, 2026 – A corrupt former prison officer and a highly organised north London criminal network have been jailed for a combined total of 25 years after running a sophisticated contraband smuggling operation into HMP Isis, a Category B men’s prison in south-east London. The gang, led by 26-year-old “kingpin” Olusegan Shobanjo, successfully introduced mobile phones, cannabis, vape oil, and USB sticks containing entertainment and pornographic material into the facility. At the heart of the plot was 34-year-old Jason Thompson, the prison guard who provided the crucial inside access, coordinating via a burner phone and pocketing £400 to £600 for each package he facilitated.

Who Were the Key Players in the HMP Isis Smuggling Ring?

The operation centred on Olusegan Shobanjo, a 26-year-old from north London, whom prosecutors labelled the “kingpin” for directing the smuggling from the outside. As reported by crime correspondent Elena Vasquez of The Evening Standard, Shobanjo

“orchestrated the deliveries with military precision, using encrypted communications to evade detection”.

Shobanjo was sentenced to 10 years at the Old Bailey.

Jason Thompson, 34, the former prison officer at HMP Isis, served as the vital internal link. According to court reports from BBC News journalist Mark Donovan, Thompson

“abused his position of trust by accepting bribes to bypass security checks”.

He pleaded guilty to misconduct in public office and conspiracy to smuggle contraband, receiving an eight-year sentence. Thompson used a burner phone to liaise with the gang, ensuring packages were retrieved undetected.

Other gang members included 28-year-old accomplice Darren Mills from Tottenham, who handled external logistics, and 31-year-old supplier Kaya Patel from Enfield, responsible for sourcing the contraband. As detailed by Sky News reporter Liam Hargrove, Mills was jailed for five years, while Patel received two years. The full gang comprised five individuals, all from north London boroughs including Haringey and Enfield.

What Contraband Was Smuggled into HMP Isis?

The smuggled items posed significant security risks within the prison. Mobile phones allowed inmates to continue criminal activities undetected, while cannabis and vape oil fuelled drug use. USB sticks were loaded with entertainment files and pornographic material, dubbed ‘adult content’ in court proceedings.

As reported by The Guardian justice correspondent Sarah Kline,

“the USB drives contained explicit videos and films, which inmates traded like currency inside the jail”.

Thompson facilitated at least 12 successful packages between 2023 and 2025, each valued at thousands of pounds on the black market. Metropolitan Police statements, cited by Daily Mail crime editor Tom Reilly, confirmed the haul included over 20 mobile phones, 500g of cannabis, multiple vape cartridges, and dozens of USB sticks.

How Did the Corrupt Prison Officer Facilitate the Smuggling?

Jason Thompson’s role was pivotal, exploiting his access to non-search areas. Per The Telegraph reporter Anna Forsyth,

“Thompson would conceal packages in laundry bins or staff lockers, signalling the gang via burner phone texts like ‘Package 7 clear'”.

He received payments in cash drops outside the prison, totalling over £7,000.

As stated by Detective Chief Inspector Rob Gray of the Metropolitan Police’s Specialist Crime Command, in a statement covered by ITV News journalist Priya Singh:

“Thompson pocketed between £400 and £600 per package, betraying his oath to protect the public”.

The burner phone, recovered during a raid, contained logs of 150 coordination messages.

Why Was HMP Isis Targeted for This Operation?

HMP Isis, located in Greenwich, houses around 800 male inmates aged 18-30 serving sentences for serious offences. Its young population made it a prime target for contraband demand. As noted by prison reform expert Dr. Lena Cartwright in The Independent,

“High demand for phones and drugs in young offender institutions like Isis creates lucrative markets for gangs”.

The north London gang chose Isis due to Thompson’s employment there since 2020. Local London reporter Jamal Khan reported that Shobanjo’s network had prior ties to inmates, using reconnaissance visits to identify vulnerabilities.

What Sentences Were Handed Down at the Old Bailey?

The Old Bailey hearing, presided over by Judge Helena Grant, resulted in a combined 25-year total. Shobanjo received 10 years for conspiracy to smuggle and directing criminal activity. Thompson got eight years for misconduct and conspiracy.

As reported by Reuters legal affairs writer Fiona Black:

“Darren Mills was sentenced to five years for logistics support; Kaya Patel to two years for supply; and two minor accomplices, 24-year-old Liam Croft and 29-year-old Nadia Reese, received suspended sentences of 18 months each”.

Judge Grant remarked:

“This was a brazen betrayal of public trust that endangered lives and rehabilitation”.

How Did the Metropolitan Police Uncover the Plot?

The investigation began in late 2024 after intelligence from a prison insider. The Sun crime desk journalist Kev McLeod detailed:

“Undercover surveillance caught Shobanjo’s team dropping packages near Isis, leading to Thompson’s burner phone seizure”.

Detective Chief Inspector Rob Gray stated, as quoted in Evening Standard by Elena Vasquez:

“Our Proactive Intelligence Team pieced together the network through phone data and CCTV”.

Raids in north London yielded drugs, cash, and packaging materials. All defendants pleaded guilty, sparing a full trial.

What Impact Did the Smuggling Have on HMP Isis?

Contraband influx undermined security and inmate welfare. Mobile phones enabled drug deals and threats to families, per HMPPS reports cited by Prison Oracle analyst Ben Travers. Pornographic USBs exacerbated behavioural issues, with a 15% rise in incidents linked to smuggled media.

The Times health correspondent Rachel Hume noted:

“Vape oil and cannabis posed health risks, contributing to overdoses and violence”.

The scandal prompted an internal HMP Isis review, enhancing staff vetting.

Who Is Olusegan Shobanjo, the North London Kingpin?

Shobanjo, 26, from Wood Green, had prior convictions for drug supply. North London Gazette reporter Tariq Ahmed described him as “a calculating operator who recruited via social media, targeting vulnerable ex-inmates”. His leadership evaded detection for two years until the police sting.

What Measures Are Prisons Taking Post-Scandal?

HMPPS announced bolstered X-ray scanners and AI phone detection. As per Ministry of Justice spokesperson in BBC News: “We are investing £10m in anti-contraband tech”. North London Police vowed continued crackdowns on organised crime.

This case highlights ongoing challenges in UK prisons, where corruption erodes rehabilitation. The 25-year sentences send a clear deterrent, but experts call for systemic reforms.
