Six Bulgarians Jailed in UK for Russia Spy Ring Operating “On an Industrial Scale”

A London court lashes out at an espionage network orchestrated from the English coast, directed by fugitive Jan Marsalek.

A London court has sentenced six Bulgarian nationals to lengthy prison terms for orchestrating a large-scale espionage ring operating in the UK and across Europe. Orlin Roussev, 47, the ring’s ringleader, received a sentence of 10 years and 8 months after pleading guilty to leading six sophisticated intelligence operations that threatened the national security of the UK, The Guardian reported.

His deputy, Biser Dzhambazov, aged 44, was sentenced to 10 years and 2 months, while Katrin Ivanova, one of the female agents recruited as part of “honeytrap” schemes, got 9 years and 8 months. Fellow operative Vanya Gaberova received a sentence of 6 years, 8 months, and three weeks, and Tihomir Ivanchev, hailed as a competitive swimmer utilized for surveillance, was handed 8 years after accounting for good behavior.

The final defendant, Ivan Stoyanov, pleaded guilty late in the proceedings and received 5 years and 3 weeks. All the sentences reflect sentencing at London’s Old Bailey.

Spy Network’s Operations: From Great Yarmouth to Europe’s Capitals

Police investigations revealed that Roussev and his group operated from a former guesthouse in Great Yarmouth, Norfolk, which served as their surveillance command center.

Through a vast cache of espionage paraphernalia—ranging from hidden cameras embedded in Minions toys and ties to IMSI-catcher devices targeting mobile phone data—they executed operations across the UK and countries including Austria, Germany, Spain, and Montenegro.

Commanders from Scotland Yard’s Counter Terrorism Command described the ring as “spy activity on an industrial scale,” emphasizing its unprecedented scale and sophistication.

Jan Marsalek: The Fugitive Handler

Jan Marsalek, a fugitive now believed to reside in Russia, coordinated the espionage cell. A former executive at Germany’s Wirecard scandal, Marsalek is wanted in Austria and Germany for fraud and is reported to have channeled intelligence instructions to Roussev through encrypted channels.

Between 2020 and 2024, they exchanged over 70,000 Telegram messages, some of which referenced potential abductions of journalists and high-value targets, media reported.

Honeytraps and Love Triangles: Personal Affairs Fuel Espionage

Within the network, personal relationships played a central role. Dzhambazov managed both Ivanova and Gaberova, allegedly deceiving one by pretending to have cancer and engaging in a romantic entanglement, The Times wrote.

Ivanova—labeled as the group’s “chief minion” in prosecution documents—was tasked with booking travel and logistical support, including plans involving IMSI-catcher devices at U.S. military bases in Germany. Her lawyer argued she had limited awareness of the operation’s full scope and was manipulated emotionally.

Plot Targets and Threat Impact

The spies targeted high-profile individuals, including investigative journalists such as Christo Grozev of Bellingcat, dissidents, diplomats, and even Ukrainian military personnel believed to be training at a U.S. base near Stuttgart.

One discussed plot involved deploying Gaberova as a honeytrap to ambush a journalist reporting on Russian activities, while another considered dropping 100 liters of pigs’ blood on the Kazakhstan embassy in London. Authorities stressed the espionage posed serious national security concerns and jeopardized the safety of targeted individuals.
