Brendan O’Callaghan is currently facing serious legal consequences due to his involvement in orchestrating drug transactions on an encrypted platform.

Topics covered
In a recent court ruling, a man from County Armagh has been sentenced for his significant role in a drug trafficking operation using the highly encrypted communication network known as Encrochat. Brendan O’Callaghan, 37, received a prison term of five-and-a-half years after being found guilty of multiple drug-related offenses spanning nearly two years.
O’Callaghan, from Armaghbrague Road in Tassagh, appeared before the Belfast Crown Court via video link from HMP Maghaberry. Judge Neil Rafferty KC emphasized the seriousness of O’Callaghan’s actions, which occurred between November 9, 2018, and July 7. His criminal activities were conducted through coded language and various aliases on the Encrochat platform.
Operational details of the drug trade
The Encrochat network became well-known for its strong encryption, making it a common choice among organized crime groups. In this instance, O’Callaghan was identified by several aliases, including securemail, Oldwinter, and BMAN. French authorities successfully infiltrated this encrypted communication system, resulting in substantial advances in various criminal investigations throughout Europe.
Police executed multiple searches of O’Callaghan’s residence, uncovering mobile phones that underwent forensic analysis. These examinations uncovered a significant number of messages that pointed to O’Callaghan’s active involvement in drug distribution. Notably, he was recorded negotiating the purchase of herbal cannabis, referred to colloquially as ‘cabbage’ or ‘green,’ on March 30.
Further evidence of drug dealings
Subsequent messages captured on April 1 revealed O’Callaghan offering users cocaine under the alias securemail, along with a stockpile of cannabis resin valued at approximately £28,750. These exchanges highlighted his extensive involvement in the drug trade, with discussions revealing plans to acquire cocaine, cryptically referred to as ‘paint’. Financial transactions discussed included a substantial £20,000 payment for what was designated as a Class A drug.
The investigation further unveiled a record of debts amounting to £100,000 tied to various drug shipments. O’Callaghan’s messages also hinted at the distribution of Xanax and Diazepam, underscoring the breadth of his criminal activities.
Legal proceedings and sentencing
O’Callaghan pleaded guilty to 16 charges, which included supplying drugs, offering drugs for sale, and conspiring to possess cocaine with the intent to distribute. He also admitted to charges related to the possession and transfer of criminal property. During sentencing, Judge Rafferty considered O’Callaghan’s troubled background, which included a challenging upbringing and ongoing mental health issues exacerbated by drug dependency.
In a statement to a probation officer, O’Callaghan acknowledged that his initial drug purchases for personal use led to connections that facilitated his role in buying and selling narcotics. The judge observed that O’Callaghan, despite a diagnosis of a learning disability, was capable of navigating the complexities of the drug trade.
Judicial considerations and aftermath
Judge Rafferty highlighted several aggravating factors in the case, notably O’Callaghan’s leadership role within the criminal operations. His strategic use of the Encrochat platform to evade law enforcement was a significant concern. The judge noted the persistence of O’Callaghan’s criminal activities, even following police interventions.
In addition to the five-and-a-half-year prison sentence, O’Callaghan is now subject to a five-year Serious Offences Prevention Order. This ruling reflects ongoing efforts to dismantle organized crime networks that exploit encrypted communication technologies for illegal purposes. The judge also ordered the destruction of all drugs, mobile phones, and related materials seized during the investigation. This decision marks a notable step in combating drug trafficking in the region.
