Police and military agents in Ukraine are notorious for dressing as protesters and assaulting the media

UKRAINE (INTELLIHUB) — Agent Provocateurs in the Ukraine are known to be especially aggressive, starting fights among protesters and attacking the media.
Agent provocateurs are used to instigate physical altercations between activists and authorities. Agent Provocateurs are people that work for the the government but pretend to be a part of a mob.
While under cover these agents commit acts of violence and vandalism to give the police a pretense to use force against the demonstrators.
According to Wikipedia:
Titushky (Ukrainian: тітушки; sometimes titushkos, titushkas) is a widely-used term in Ukrainian mass media and by the general public for street hooligans who are suspected to be sponsored by the government. They are alleged to be an illegal formation of combat troops dressed as civilians, whose goal is to assault and disperse peaceful demonstrations by opponents of the government, and attack participants and representatives of the media.
Titushky blend in with a crowd or mob and then instigate a fight. During the events in Ukraine in 2013/2014 known as Euromaidan, it became a collective term for provocateurs and thugs hired by the Party of Regions[1] and law enforcement agents in civilian clothing.
The name comes from Vadym Titushko (Ukrainian: Вадим Тітушко) (also known as Vadik Rumyn (Russian: Вадик Румын)), a mixed martial artist[4]from Bila Tserkva who attacked journalists of the 5th Channel on May 18, 2013. He was one of three men who received suspended sentences over the attack. Titushko reportedly is unhappy with the association of his name.[5]
On Radio Liberty web page titushky are described as “burly guys dressed in sports gear who act as agents provocateurs.
They crack down on protesters or provoke clashes with the aim of tarnishing peaceful protests”. Not a completely new term specific to Euromaidan protests, “titushky” was devised earlier this year after two journalists were beaten up in Kyiv by a group of athletically built youth.
