A BRIT suspected traitor has been arrested in Ukraine accused of working for the Russians.
Ross David Cutmore – a 40-year-old former soldier and military instructor – had allegedly been working to supply Vladimir Putin’s agents with weapons so they could carry out assassinations.
Cutmore, from Scotlandarrived in Ukraine earlier this year to help train up troops, Ukraine’s SBU spy service told The Sun.
But he now stands accused of smuggling weapons to Russian hit squads who murdered a former MP in Lviv and an activist in Odesa.
Kyiv claim he was recruited by Putin’s ruthless FSB spy agency after being lured in by the promise of making “easy money”.
He is also accused of betraying the names of his fellow foreign volunteers and the coordinates of Ukrainian military bases to the FSB.

The Brit was detained and unmasked with the help of the British secret services including the MI6 and GCHQ, the SBU confirmed.
Cutmore now faces up to 12 years in prison after first being arrested at his Kyiv home in October – with full details only being released today.
He is being held under suspicion of passing unauthorised information to Russia.
The ex-squaddie is believed to have had British military experience, including in the Middle East.
But The Sun understands his only known service was “less than a year as a military cadet” at Glasgow University.
A source said: “He would be no more combat effective than a life boat. The OTC is basically a social club designed to give people a look at army life.”
He allegedly trained Ukrainian conscripts in the southern city of Mikolaiv, but he gave up the job September and moved to the port city of Odesa.
It was there, investigators claim, that he shared messages on pro-Kremlin websites offering to spy for money.
Cutmore had his identity covered up during his initial arrest as he was seen being hauled into court where he appeared before a judge.
Shocking details around the case have emerged since with Cutmore being accused of playing a role in several Russian assassination plots.
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 to be used in killings by Russian agents.
Ukrainian officials alleged he was preparing to commit bomb attacks.
He also received instructions on where to find a loaded pistol with two magazines.
The weapons were allegedly used to kill activist Demian Hanul, who was shot in a street in Odesa in March, and former MP Iryna Farion, who was shot outside her home in Lviv in July.
Farion infuriated Moscow for years before she was shot and killed in her home city Lviv in July 2025.
The professor was rushed to hospital after being shot in the head by a gunman.
Hanul on the other hand was was shot twice with a short-barrelled gun as he walked on a street in the Black Sea port.
Investigators are also probing claims the disgraced soldier provided firearms used to kill former Ukrainian parliament speaker Andriy Parubiy, a key anti-Russian figure.
Parubiy, former secretary of the National Security and Defence Council of Ukrainewas assassinated in Lviv in a broad daylight attack on August 30, 2025.
The killing sparked wide shock and condemnation across Ukraine – but was celebrated by hardline Russian war fanatics.
Cutmore was paid at least £4,500 for the work he did for the Russians, the SBU spy service added.
An SBU source said: “Cutmore is currently detained and in custody, and the investigation is ongoing.”
Cutmore is believed to be from Dunfermlinebut also to have lived in Rosyth.
Investigations into Cutmore are ongoing with him now in custody.
An FCDO spokesperson said: “We are providing consular assistance to a British man who is detained in Ukraine. We remain in close contact with the Ukrainian authorities.”
