                        TogglePlayerControllable(playerid, 0);
                        SendClientMessage(playerid,COLOR_RED,"You have freezed because you are not near admin");
                       }
                 }
        }
return 1;
}

Didn't test it yet,but i guess it's working

EDIT:Changed to freeze,old one would kill the player
