In order to deal with this, the police department decided to set up barricades, and police checks on every road. It did not matter if it was a main road or not, but they decided to check on every person that was using the road.
They stopped others from entering the Eastern part of the city, only allowing those that were living to pass. With that, they were able to deal with just the people that were coming from the Eastern part of the city.
But, it was quite difficult for them to be able to deal with such a large number of civilians in the Eastern part of the city. As for where they were going to, the provincial government had already organized for somewhere that they were going to stay temporarily.
