how to report a hacker?

my friend got a jett teamate who was clearly hacking and admitted it, how do i report him?

and not the in-game function, i mean email or any type of outer communication

was he in your game? should be easy then. post match screen u hover over his name and click report.

edit: ah, dunno - havent had that kind of cheater experience yet

click on report option

You can report them from here (u need to know the name and tagline): https://support-valorant.riotgames.com/hc/en-us/articles/360050787693-Report-Players-After-Game-Here
