By Tania Kharchenko and Samuel HortiBBC Eye Investigations7 July 2026, 00:55 BSTThis article contains accounts of torture and sexual violenceEarly one October morning in 2019, a group of men jumped out of a car and grabbed Liudmyla Huseinova as she left her home.The 64-year-old says they seized her bag and threw her into the back seat, beginning what she describes as a “nightmare” in Russia’s secretive detention system in parts of Ukraine it had occupied since 2014: “For three years and 13 days of my life, my soul and body were crippled.”She says that among the men was Yurii Temerbek, a Ukrainian who had been a local traffic policeman and had joined the Russian-backed separatists.Temerbek – a husband, father and grandfather, now aged 56 – was there again, two weeks later, she says, watching as a man with a Russian accent sexually assaulted her in a notorious detention centre.A BBC World Service investigation has identified Temerbek, and uncovered details about two other men accused of abusing detainees, shedding light on a system that operates almost completely out of reach of Ukrainian and international justice.The men appear to now be living ordinary lives with their families in Russia and occupied Ukraine. Survivors see revealing their identities as a step towards holding them accountable.Liudmyla says that if the men she accuses of abuse aren’t found and imprisoned, “then, justice for me will be their names as criminals, and torturers, will be known to their children”.OK.ruThe prisons these men helped run are part of a detention system in which the UN’s human rights office (OHCHR) says the torture and ill-treatment of civilians is “systematic and widespread”.It says former detainees describe beatings, electric shocks, mock executions and sexual violence, with civilians often detained arbitrarily and families given little information.The Kremlin has accused the OHCHR of bias. In May this year, the UN added Russia to its blacklist of countries suspected of committing sexual violence in conflict zones – allegations Russia dismissed as “groundless lies”.Ukrainian authorities say more than 16,000 civilians have been taken captive or disappeared. Some of these cases followed Russia’s full-scale invasion of Ukraine in 2022 – others date back as far as 2014, when Russia annexed the southern Ukrainian peninsula of Crimea and occupied parts of eastern Ukraine, triggering widespread international condemnation.At that time, Liudmyla was working as a safety engineer on a poultry farm in Novoazovsk, a city in the Donetsk region close to the border with Russia.Russian-backed armed groups seized the city, beginning several years of paramilitary control.Liudmyla says that, under occupation, she helped care for orphans and took food to Ukrainian forces, who gave her a Ukrainian flag with notes of thanks written on it. She believes a photo of the flag she shared with trusted friends reached the Russian-backed forces: “This was probably why they arrested me.”She was accused of spying, she says, and taken to Izolyatsia – a factory-turned-modern art gallery that had been taken over by Russian-backed forces. It later became widely known and feared, as numerous accounts of torture emerged from former detainees.When she arrived, she says a group of men – she does not know who – surrounded her, pinching her body. “It’s not a peach,” she recalls one of them saying. “Not a dried apricot either. A raisin.”Detainees were forced to stand constantly from 06:00 to 22:00, and bright lights shone at night, she recalls. Her first days, she says, were punctuated with sounds of distress from other rooms: “I have never heard such terrible screams before.”Two weeks later, she says, she was taken to the second floor, where a man who was referred to as “Koval” in the prison told her she was “too old for boys who come for ‘relaxation'”.Temerbek was there, “being sarcastic… laughing”, she says.Then, she says, Koval sexually assaulted her.She knows Temerbek’s name, she explains, because she saw his name on a document and remembered he had been known locally for his role in the Ukrainian police.Ukrainian authorities accuse him of working for the Ministry of State Security (MGB) established by the Donetsk People’s Republic (DPR), which was created by Russian-backed paramilitaries.Ukrainian prosecuto …
