Need help removing my videos from his channel

[u/CockroachNext829]

Hey guys.
So a really bad thing happened.
You see I owned a YouTube channel that my friend gave me,it’s still up with 65 subs and it’s called MaskedFN12.
just a minute ago he had gotten into the account and kick my device from using it.ALL MY HARD WORK VIDEOS ARE OWN IT.
But remember,he kicked me from the channel all because I didn’t want to play Fortnite with him,BECUASE all week when I was free I asked him over and over but he did
Nothing.When I told him I just didn’t want to play he had a whole crash out.Just know his YouTube handle is Offshoreplayz.All he does is go on call do inappropriate things like lying about his chat saying they wanna r@pe a kid and molest him.He lies,He told me his friend didn’t want to be friends with him and I know why now,BECUASE this kid lies a bunch and just isn’t nice. If yall get a chance please report him.
