During a second day of local protests against immigration reform by El Paso High Schoolers, Police felt threatened enough to pull out their riot gear.

The day started peacefully as about 200 students from Canutillo High walked out as class was beginning Thursday morning. Shortly afterward students at Del Valle, Ysleta and Irvin High schools also left campus. At mid-morning, Police were dispatched to El Dorado, Coronado and Franklin High Schools in an effort to keep students in class.

In some instances, Police had to stop traffic as students were walking on the street. Along with El Paso Police, EPISD and Sheriff's Officers all responded to walkout incidents.

Thursday afternoon, 200 Del Valle and Ysleta students joined in a march to the border. Shortly after 2pm, Alameda was temporarily closed at Loop 375 as students marched across. Bernice Zubia spokesperson for the Ysleta school district told KFOX that "The Ysleta District does not endorse or promote any of these walkouts although we do realize that some of our students have concerns." Zubia said the district has sent a phone message to parents to encourage their children to remain in class.

El Paso Police say they were not prepared for this student protest because the students did not give them a heads up.

"When something happens like on an emergency basis like today, where it just ends up erupting, we got to pull everybody and put them in uniform and really puts a strain on the shortage that we are already enduring," Officer Linda Olvera from the El Paso Police Department told KFOX.

Officer Olvera said this causes problems when there is a real emergency situation or when things get out of hand. Late Thursday afternoon, police felt threatened enough to put on their riot gear after some students started pushing a bus that police brought in to them home after the protest.

Police said they were able to calm the situation down, and did not have to use any force against the students. By the end of the day, students walked out of a dozen El Paso schools, but were well outnumbered by the number of students who decided to stay in class.

Police tell KFOX that they will be prepared for Friday's Cesar Chavez March because they did get notice about this march.
