A Hamilton High School student has been arrested after Chandler police say he made threats against the school.
Police say the 17 year old posted a picture online of a cartoon gun and a warning not to go to school on Monday.
"Once it hit social media we had responses coming in from all over the country." said Sgt. Joe Favazzo with the Chandler Police Department.
Police say the student posted the warning Sunday night.
Hamilton High School students and parents saw it and called police.
The student - who we are not identifying because he is juvenile - later posted an apology online, saying that the warning was mean as a joke.
"I did not mean it at all. I do not own any weapons at all. Please understand that I didn’t mean for this to happen. I will never do it again," said the student.
"We're not just gonna say oh this was a joke and walk away. This is a very serious matter," said Sgt. Favazzo.
Police say the teenager is facing potential charges of making threats and disrupting school functions.
School district officials say more than 25% of the students at Hamilton called out of school because of the threat.
