Police said Audrey Nicole Francisquini, 28, snuck into American Senior High School in Hialeah, Miami-Dade County, on Monday morning (10 May).
After being arrested, she was charged with burglary, interference with an educational institution and resisting an officer without violence.
According to the arrest report, she had been able to blend in with other students by wearing a backpack, dressing similarly to them and carrying a skateboard.
Once inside, she approached students and handed them pamphlets with her Instagram details printed on them, asking them to follow her page.
The report said Francisquini was also using her phone to record herself while walking through the school.
After school administration was advised of a 'potential threat on campus', security guards found her wandering through the halls and confronted her, but she simply told them she was trying to find the registration office.
However, the police report said that instead of making her way to the office, she continued to walk through the school stopping students - eventually being stopped by security for a second time.
After refusing to stop what she was doing, Francisquini left the building and fled the school property, with CBS News reporting she left through a side door leading to the faculty parking lot.
But this wasn't the end of the story, as police were fortunately able to use her Instagram account to find her.
Francisquini was arrested at her home in North Miami Beach and booked into Miami-Dade jail. She remained on a $2,000 bond on Tuesday, according to NBC Miami.
After being arrested on Monday, Francisquini was charged with one felony count of burglary of an occupied dwelling, a misdemeanour count of trespassing an educational institution/interference and one misdemeanour count for resisting an officer without violence, according to Miami-Dade online court records.
A Miami-Dade County Public Schools spokesperson said in a statement: "A thorough review of this matter is underway.
"As always, Miami-Dade County Public Schools will continue to work tirelessly to protect the safety and wellbeing of our students and employees."
