MIAMI -- Two Kendall teenagers accused of vandalizing a southwest Miami-Dade County Islamic school face more serious charges because of evidence of prejudice, police said.

Michael Lobo and Juan Carlos Gonzalez, both 17, admitted to police they had been planning the attack on the school for months and said they believe "all Muslims are terrorists," according to their arrest forms.

Members of the mosque and school who attended prayers Friday expressed disappointment at the news.

"We don’t want any harm to those kids. Kids are kids; we need to find out who's teaching them," said Omar Zaveri. "Somebody is teaching them, fueling their hatred."

Police said a tip to Crime Stoppers led them to the boys, who were both arrested Thursday evening. Lobo was arrested at his home and Gonzalez was arrested at Killian High School. The boys live within two blocks of each other in a Kendall subdivision. Attempts to reach the families at both homes were unsuccessful.

According to the arrest form, the boys confessed to planning the June 26 attack for months. They smashed two windows at the school with iron bars and slashed the tires of a van used to feed the homeless, police said.

The teens also planned to spray paint expletives against Muslims on the walls, but the spray paint can they bought was missing a nozzle, according to the arrest form.

Lobo is student at Westwood Christian School. Gonzalez attended Killian Senior High School.

"It's kind of sickening and disheartening. They are young kids, young kids that obviously have parents that are teaching them hate," said Nidal Hozien, a representative of the Islamic School of Miami.

The school and mosque has been the target of several attacks in recent years.

Last New Year’s Eve, someone fired a barrage of more than 50 bullets around the mosque’s gold dome. Pock marks from the bullets are still evident in the cement walls and metal dome.

Rashid Laher from the United Kingdom was visiting the mosque.

"I think people of faith across Miami need to stand together to show there is unity amongst people of faith," said Laher.
