It happens in Romania with Adrian Nastase, the former Romanian PM, being chased by the Anti-Corruption Department for, what else, corruption accusations. The problem is that the procedures are rather twisted and complicated because of the messy legislation (inherited from Nastase's net created while he was in the office) and besides there are several politicians from both the opposition and the government creating obstacles or bringing procedure-related criticisms (most likely because that would shake the system and bring out some nasty stuff). 

However, the political will is there and hopefully justice will be done - the Romanian Justice Minister and her staff seem very commited to do a good job. FT has a good article with more details on the entire context.
