Can i DO anything Former Riot Employee Stole my Name

Hello there i want to ask if i can get any help from anywhere to get help to get my account name back a friend of myn is trying to help me by making this post which explains the issue Thanks for looking. I never Changed my name or Region.

It all started when he (Summoner name: Gangster) tried to log in one day and his password did not work and the game told him that his account was "transferred to another region". My friend has a degree as a Network Specialist, has been fixing computers for the last 5 years, never had a keylogger or clicked on suspicious links, and he recently reinstalled his operating system. It is not likely that his account was compromised.
Apparently, Coronach (a former Riot employee, http://leagueoflegends.wikia.com/wiki/Steven_%27Coronach%27_DeRose) changed his summoner name to Gangster (my friend's old summoner name). We have no idea how this happened. He has already emailed Riot support but they are not doing anything about this as of yet. He would like some insight into this matter from a Rioter since there are so many that read Reddit.
PROOF: http://www.lolking.net/summoner/na/216#history (As of May 27, clicking on Coronach's name in this guy's match history redirects to http://www.lolking.net/summoner/na/631 (Gangster) and the champions played between this new 'Gangster' and Coronach match up.) This only happens on LoLKing when someone recently changes their summoner name and their old name sticks around in the LoLKing match history for a few days/weeks. This makes us suspicious that something must have went awry in Riot's database. Being a former Riot employee, Coronach, may have insight into how and why this was done.
UPDATE: My friend's lolking profile: http://www.lolking.net/summoner/na/144026#profile (still shows his name as Gangster) compared to his elophant profile: http://www.elophant.com/league-of-legends/summoner/na/144026 apparently his new name is BigfatAutoMatik.

 
Alright, so what you are saying is basically: this guy (game dev of LoL) stole your (some random nobody) account, changed the name and region, whereby risking his integrity, any future jobs, media uproar, etc. just to screw with you?

Its more than likely your account got hacked(read: keylogged) and someone changed your char name. If thats even possible to do. (not much of a LoL fan.)
 
so what your saying is if someone hacked my account and this guy got my name the very day i get hacked ? and just happens to be a former riot employee ? who just happened to want to change his name that same day to my name ?? this just seems very suspicious and i seriously doubt i got key logged i know what i am doing i fix computers for a living. And as far as i am aware you have to pay riot to change your name which would further prove i did not pay for such a thing. and i did some research on Google this is not the first time this has happened.
 
stealing my account name has obvious reasons its named gangster no one can get this name its pretty exclusive i got it in beta of the game i also have skins in game that cannot be bought anymore he did not change anything in my account he just TOOK my NAME inside game. and i was renamed to some other name but i still do not have access at the moment to even that account name.
