So here's what happend.

I was on the roof at Server 1 Spawn handling F1's and this guy stood below us throwing his machete,suiciding and throwing his new ones again. He hit me and the ones I was dealing with.

I froze him and told him to stop doing it, after I was done with my F1's I went down to the Spawn area and saw him killing a guy(apparently his friend), a police officer and a radio manager infront of me. It seemed to be like Mass RDM and went straight ahead to ban him.

I gave him a verbal warning before and It didn't look like he was about to stop anytime soon.
A 60 minute ban is reasonable in my opinion.
