Found a hacker, please report him

So i joined his team through random match up, we all landed on farm and began looting. A few mins later I see he already is at his 10 th kill. I started following him, moving with him in his vehicles and such, he was clearly spotting enemies from far away and rushing towards they very fast. Probably had movement hack along with other stuff. He got 23 killstthat game alone. Upon confronting he says it's not his only account lmao
