Ukrainian police have launched what appears to be a campaign of intimidation as protests continue to grip the country.
Dimitri Bulatov, leader of the largest protest group, went missing five days ago after weeks of receiving threatening calls and attacks on his business.
A makeshift hospital was also reportedly smashed by police and medical workers said they feel intimidated.
Three people were killed last week during demonstrations and opposition leaders say dozens have gone missing.
