Is there hacking on League?

[quote=zzzKevin]I was playing a game with my friends and during the end of the match when we were winning, the enemy vlad just teles out of nowhere (He didn't have summoner skill) into our base near us and wiped us out. He would also kill us from far away with his pool or Q and wouldn't receive damage from skills,turrets, or regular attacks. The only skills that affected him were Skill shots. Can anyone explain this?[/quote]

[quote=hypershatter]there are no hacking on league that involves changing the game play mechanics. however, there was a rumored hack before that disconnects players. but that was a long time ago.[/quote]
