Hi, today I was playing on official server and got killed two times by an invisible cheater. I got killed 2 times and then I left the server.

Server: DayZ EU DE 1297 (1st Person Only)
My steam ID is 76561198954841832.
First time I got killed was around 20:05 GMT+2 and the second time was around 20:12 GMT+2. The first time it happened when I was in a house I belive it was Elektrozavodsk, preparing to cook my chicken, firstly a car drove past, then some weird effects happened and then I just died. Second time I was in a railroad station and grenades started flying at me out of nowhere. He also snapped my neck and i could just look backwards. I belive he was terorrizing the whole server like this.
I also have videoproof if you need it.

Thanks,
David
