RIO DE JANEIRO (AP) — Brazilian organizers brought in 600 extra security forces Sunday and put up higher perimeters fences for the World Cup game at the Maracana Stadium after ticketless fans broke into the venue at both previous matches there.

Around 40 police officers lined up behind new fences at the specific part of the stadium where nearly 100 Chilean supporters forced their way in ahead of Wednesday’s Spain-Chile game, then rampaged through the press center breaking down walls in an apparent attempt to get in to the sold-out match.
