Is your in-game name Ethen Nicks? If so, you are suspended and you probably have an active investigation going on. You have most likely been contacted by IA or will be contacted by IA on plpd.online asking you for a statement.
If you go to plpd.online > Internal Affairs > Complaints, then you will be able to see 'open complaints on you'. If there is nothing there you should make a helpdesk ticket.
