Ross Black, a 33-year-old former welder from Dalgety Bay in Fife, has been sentenced to four years in prison at the High Court in Edinburgh after his involvement in cocaine supply was uncovered through a financial investigation triggered by his bank.
Black, who was unemployed and had not paid tax or national insurance since February 2021, was discovered with £709,623 across cash, bank, and savings accounts. He admitted to involvement in the supply of cocaine between October 2022 and October 2023, as well as acquiring and possessing criminal money on various occasions between April 2021 and October 2023.
Lord Judge Summers indicated that Black would have received a six-year sentence for the offending but reduced the term to four years in recognition of his guilty pleas.
How did the investigation begin?
The investigation commenced when Black opened a Monzo bank account in May 2023, claiming to be employed on a production line in the manufacturing industry. According to court records, police received information about the account in July 2023. Over a two-month period, the account showed a turnover of approximately £43,724.
Advocate depute Naomei Warner explained that the bank's automated systems flagged the activity because the turnover far exceeded the institution's expectations for someone in Black's stated line of work. Further inquiries revealed that Black also maintained a current account with another bank and held multiple savings accounts.
The prosecutor told the court that Black received a constant stream of round-figure sums from approximately 300 individuals. When payments were made, references appeared to "gear", "rent", and "flights"—terminology consistent with drug dealing operations.
What triggered the arrest?
A Crown Office serious organised crime unit initiated a money laundering investigation into Black's financial activity. Warrants were granted to search for evidence of drugs and the proceeds of criminal offences. According to the court proceedings, police were en route to execute these warrants when officers spotted Black driving a Nissan Juke and followed him to an address in Cardenden in Fife.
Upon detention, Black indicated that drugs belonging to him were in the vehicle. Officers discovered 17 dealer bags of cocaine with an estimated street value of approximately £1,500. Testing revealed the cocaine had a purity level between 76 and 79 percent, indicating it had not been adulterated.
Warner told the court that expert drug officers concluded the high purity level was
demonstrative of the accused having access to, or involvement with, serious organised crime groups as access to import purity cocaine is restricted to such groups.
A mobile phone recovered from Black contained messages discussing cocaine supply and money exchanges. A subsequent search of his home address yielded more than £10,000 in cash.
What was Black's employment history?
Black last declared income from employment in the tax year 2019-20, meaning he had been without reported income for nearly two years before opening his Monzo account. His claim to be working in manufacturing was entirely fabricated, serving as cover for his drug trafficking activities.
The contrast between his stated unemployment and the substantial sums flowing through his accounts was precisely what triggered the bank's compliance systems and ultimately led to his detection.
What happens next?
The Crown is now pursuing the recovery of crime profits from Black. According to court information, sentencing had been deferred for a background report, indicating that further proceedings were expected to determine the full extent of asset recovery.
This case reflects a broader pattern of drug trafficking prosecutions in Scotland. Earlier this year, a man was jailed for over three years after being caught with £300,000 worth of cocaine in Glasgow, while another fugitive received a five-year sentence for involvement in a £14 million drugs and cash network.
