A BRIT suspected traitor has been detained in Ukraine accused of working for the Russians.
Ross David Cutmore – a former Royal Marine and military instructor – allegedly had been working to supply Putin’s agents with weapons for assassinations.
Cutmore, believed to be in his early 40s and from Scotland, arrived in the Ukraine earlier this year to train troops, according to the SBU security service in Kyiv.
Intelligence sources in Kyiv reportedly said he was detained with the help of the British secret services.
The ex-squaddie had British army experience, including in the Middle East, say Ukrainian sources.
The Russian special services provided Cutmore with firearms and ammunition “to carry out targeted killings on the territory of Ukraine,” alleged the SBU.
He is accused of “reconnaissance and sabotage activities” and bringing weapons into the country for killings by Russian agents.
In particular, he is suspected of providing firearms used to kill former Ukrainian parliament speaker Andriy Parubiy, a key anti-Russian figure, according to Ukrainian Pravda.
Parubiy was assassinated in Lviv — shot dead in broad daylight – on 30 August 2025.
He was earlier secretary of the National Security and Defence Council of Ukraine.
The killing sparked wide shock and condemnation across Ukraine – but was celebrated by hardline Russian war fanatics.
Cutmore is also suspected of providing firearms for the murder of Ukrainian nationalist and former MP Irina Farion, 60, who infuriated Moscow was shot and killed in her home city Lviv.
A professor, she died in July 2025 after she was rushed to hospital after being shot in the head by a gunman.
The third assassination linked to the British military trainer was Demyan Hanul, 31, a Ukrainian nationalist campaigner wanted by Russia, who was gunned down in Odesa in March.
He was shot twice with a short-barrelled gun as he walked on a street in the Black Sea port, said reports at the time.
An SBU source said: ‘Cutmore is currently detained and in custody, and the investigation is ongoing.”
Ukrainian Pravda said: “The SBU counterintelligence service, in cooperation with British special services, exposed Ross David Cutmore, a British citizen who, on behalf of Russian special services, carried out reconnaissance and sabotage activities in Ukraine in 2024-2025.”
Cutmore is believed to be from Dunfermline, but also to have lived in Rosyth.
