Matios told Ukraine's Channel 5 television station that the fighters are holed up in Boyarka, a town southwest of the city.
"I don't know what the Tornado company is doing, armed, in Boyarka. Right near Kiev there are many armed men who have not disbanded [from their formations]. Where is the Internal Affairs Minister? Why can't he monitor the implementation his own order?!"
Last month, Ukrainian law enforcement detained eight fighters from the Tornado special police unit, including company commander Ruslan Onishchenko, suspecting them of committing serious crimes against the civilian population in the Ukrainian-controlled portion of the Lugansk region.
Ukrainian Internal Affairs Minister Arsen Avakov had signed an order disbanding the police unit back in June. The militants had initially resisted, responding to the order by mining the territory around their Severodonetsk base, blocking off the path to the base and threatening to open fire on government forces. The militants later abandoned the territory, and Ukrainian security organs have carried out an investigation.
The Tornado special police unit has been accused of committing horrific crimes during its service in Donbass, including murder, rape, assault, kidnapping, looting and racketeering. The group recorded much of their gruesome behavior, including the gang rape of a local man, on video.
