A German man with a history of black market banking allegations was recently sentenced to three years and 10 months in prison for moving 33 million euros in illicit funds through the international financial system.
Gerard Grischew was sentenced on June 10 in the Berlin Regional Court after pleading guilty to charges of forging documents and operating an unregistered banking system. He will appeal the length of his sentence, his lawyers told the court.
Prosecutors said Grischew used forged IDs and strawmen to set up more than dozen companies with accounts at German banks. He allegedly used those accounts to move 33 million euros for his clients from May 2022 until he was arrested in October 2025.
At that time, he was already serving a suspended prison sentence for a similar scheme, for which he was arrested in 2021, prosecutors said.
Grischew’s defense team did not respond to OCCRP requests for comment.
According to police testimony during his Berlin trial, Grischew’s unlicensed payment system accepted international bank transfers from clients and returned funds to them in cash; it also accepted cash from clients and then secretly transferred funds on their behalf, including for payments for drugs in Latin America.
All of the money that went through Grischew’s fraudulently opened bank accounts was converted into cryptocurrency to obscure the money trail, the police witness told the court.
Grischew received a four-year suspended sentence in February 2022 for operating a similar black market banking system from 2019 to 2021. That unregistered banking system allegedly handled 6.5 million euros stolen from Germans in a cyber-trading scam operated by Timur R., who is not German.
The Bamberg Regional Court sentenced Timur R. to 4.5 years in prison for the cyber-trading scam in August 2025. In that case, Ukrainian authorities also confiscated a Lamborghini and Rolls Royce from Timur R. in Kyiv and transferred them to German authorities to raise funds to compensate scam victims.
Prior to his 2021 arrest in Germany, Grischew was tried and acquitted in the U.K. on allegations that he was the head of an international money laundering organization. Grischew's former defense lawyer Kieran Vaughan KC highlights the details of that case on a website advertising his legal services.
